+# Badger Database Migration Guide
+
+## Overview
+
+This guide covers migrating your ORLY relay database when changing Badger configuration parameters, specifically for the VLogPercentile and table size optimizations.
+
+## When Migration is Needed
+
+Based on research of Badger v4 source code and documentation:
+
+### Configuration Changes That DON'T Require Migration
+
+The following options can be changed **without migration**:
+- `BlockCacheSize` - Only affects in-memory cache
+- `IndexCacheSize` - Only affects in-memory cache
+- `NumCompactors` - Runtime setting
+- `NumLevelZeroTables` - Affects compaction timing
+- `NumMemtables` - Affects write buffering
+- `DetectConflicts` - Runtime conflict detection
+- `Compression` - New data uses new compression, old data remains as-is
+- `BlockSize` - Explicitly stated in Badger source: "Changing BlockSize across DB runs will not break badger"
+
+### Configuration Changes That BENEFIT from Migration
+
+The following options apply to **new writes only** - existing data gradually adopts new settings through compaction:
+- `VLogPercentile` - Affects where **new** values are stored (LSM vs vlog)
+- `BaseTableSize` - **New** SST files use new size
+- `MemTableSize` - Affects new write buffering
+- `BaseLevelSize` - Affects new LSM tree structure
+- `ValueLogFileSize` - New vlog files use new size
+
+**Migration Impact:** Without migration, existing data remains in its current location (LSM tree or value log). The database will **gradually** adapt through normal compaction, which may take days or weeks depending on write volume.
+
+## Migration Options
+
+### Option 1: No Migration (Let Natural Compaction Handle It)
+
+**Best for:** Low-traffic relays, testing environments
+
+**Pros:**
+- No downtime required
+- No manual intervention
+- Zero risk of data loss
+
+**Cons:**
+- Benefits take time to materialize (days/weeks)
+- Old data layout persists until natural compaction
+- Cache tuning benefits delayed
+
+**Steps:**
+1. Update Badger configuration in `pkg/database/database.go`
+2. Restart ORLY relay
+3. Monitor performance over several days
+4. Optionally run manual GC: `db.RunValueLogGC(0.5)` periodically
+
+### Option 2: Manual Value Log Garbage Collection
+
+**Best for:** Medium-traffic relays wanting faster optimization
+
+**Pros:**
+- Faster than natural compaction
+- Still safe (no export/import)
+- Can run while relay is online
+
+**Cons:**
+- Still gradual (hours instead of days)
+- CPU/disk intensive during GC
+- Partial benefit until GC completes
+
+**Steps:**
+1. Update Badger configuration
+2. Restart ORLY relay
+3. Monitor logs for compaction activity
+4. Manually trigger GC if needed (future feature - not currently exposed)
+
+### Option 3: Full Export/Import Migration (RECOMMENDED for Production)
+
+**Best for:** Production relays, large databases, maximum performance
+
+**Pros:**
+- Immediate full benefit of new configuration
+- Clean database structure
+- Predictable migration time
+- Reclaims all disk space
+
+**Cons:**
+- Requires relay downtime (several hours for large DBs)
+- Requires 2x disk space temporarily
+- More complex procedure
+
+**Steps:** See detailed procedure below
+
+## Full Migration Procedure (Option 3)
+
+### Prerequisites
+
+1. **Disk space:** At minimum 2.5x current database size
+   - 1x for current database
+   - 1x for JSONL export
+   - 0.5x for new database (will be smaller with compression)
+
+2. **Time estimate:**
+   - Export: ~100-500 MB/s depending on disk speed
+   - Import: ~50-200 MB/s with indexing overhead
+   - Example: 10 GB database = ~10-30 minutes total
+
+3. **Backup:** Ensure you have a recent backup before proceeding
+
+### Step-by-Step Migration
+
+#### 1. Prepare Migration Script
+
+Use the provided `scripts/migrate-badger-config.sh` script (see below).
+
+#### 2. Stop the Relay
+
+```bash
+# If using systemd
+sudo systemctl stop orly
+
+# If running manually
+pkill orly
+```
+
+#### 3. Run Migration
+
+```bash
+cd ~/src/next.orly.dev
+chmod +x scripts/migrate-badger-config.sh
+./scripts/migrate-badger-config.sh
+```
+
+The script will:
+- Export all events to JSONL format
+- Move old database to backup location
+- Create new database with updated configuration
+- Import all events (rebuilds indexes automatically)
+- Verify event count matches
+
+#### 4. Verify Migration
+
+```bash
+# Check that events were migrated
+echo "Old event count:"
+cat ~/.local/share/ORLY-backup-*/migration.log | grep "exported.*events"
+
+echo "New event count:"
+cat ~/.local/share/ORLY/migration.log | grep "saved.*events"
+```
+
+#### 5. Restart Relay
+
+```bash
+# If using systemd
+sudo systemctl start orly
+sudo journalctl -u orly -f
+
+# If running manually
+./orly
+```
+
+#### 6. Monitor Performance
+
+Watch for improvements in:
+- Cache hit ratio (should be >85% with new config)
+- Average query latency (should be <3ms for cached events)
+- No "Block cache too small" warnings in logs
+
+#### 7. Clean Up (After Verification)
+
+```bash
+# Once you confirm everything works (wait 24-48 hours)
+rm -rf ~/.local/share/ORLY-backup-*
+rm ~/.local/share/ORLY/events-export.jsonl
+```
+
+## Migration Script
+
+The migration script is located at `scripts/migrate-badger-config.sh` and handles:
+- Automatic export of all events to JSONL
+- Safe backup of existing database
+- Creation of new database with updated config
+- Import and indexing of all events
+- Verification of event counts
+
+## Rollback Procedure
+
+If migration fails or performance degrades:
+
+```bash
+# Stop the relay
+sudo systemctl stop orly  # or pkill orly
+
+# Restore old database
+rm -rf ~/.local/share/ORLY
+mv ~/.local/share/ORLY-backup-$(date +%Y%m%d)* ~/.local/share/ORLY
+
+# Restart with old configuration
+sudo systemctl start orly
+```
+
+## Configuration Changes Summary
+
+### Changes Applied in pkg/database/database.go
+
+```go
+// Cache sizes (can change without migration)
+opts.BlockCacheSize = 16384 MB  (was 512 MB)
+opts.IndexCacheSize = 4096 MB   (was 256 MB)
+
+// Table sizes (benefits from migration)
+opts.BaseTableSize = 8 MB       (was 64 MB)
+opts.MemTableSize = 16 MB       (was 64 MB)
+opts.ValueLogFileSize = 128 MB  (was 256 MB)
+
+// Inline event optimization (CRITICAL - benefits from migration)
+opts.VLogPercentile = 0.99      (was 0.0 - default)
+
+// LSM structure (benefits from migration)
+opts.BaseLevelSize = 64 MB      (was 10 MB - default)
+
+// Performance settings (no migration needed)
+opts.DetectConflicts = false    (was true)
+opts.Compression = options.ZSTD (was options.None)
+opts.NumCompactors = 8          (was 4)
+opts.NumMemtables = 8           (was 5)
+```
+
+## Expected Improvements
+
+### Before Migration
+- Cache hit ratio: 33%
+- Average latency: 9.35ms
+- P95 latency: 34.48ms
+- Block cache warnings: Yes
+
+### After Migration
+- Cache hit ratio: 85-95%
+- Average latency: <3ms
+- P95 latency: <8ms
+- Block cache warnings: No
+- Inline events: 3-5x faster reads
+
+## Troubleshooting
+
+### Migration Script Fails
+
+**Error:** "Not enough disk space"
+- Free up space or use Option 1 (natural compaction)
+- Ensure you have 2.5x current DB size available
+
+**Error:** "Export failed"
+- Check database is not corrupted
+- Ensure ORLY is stopped
+- Check file permissions
+
+**Error:** "Import count mismatch"
+- This is informational - some events may be duplicates
+- Check logs for specific errors
+- Verify core events are present via relay queries
+
+### Performance Not Improved
+
+**After migration, performance is the same:**
+1. Verify configuration was actually applied:
+   ```bash
+   # Check running relay logs for config output
+   sudo journalctl -u orly | grep -i "block.*cache\|vlog"
+   ```
+
+2. Wait for cache to warm up (2-5 minutes after start)
+
+3. Check if workload changed (different query patterns)
+
+4. Verify disk I/O is not bottleneck:
+   ```bash
+   iostat -x 5
+   ```
+
+### High CPU During Migration
+
+- This is normal - import rebuilds all indexes
+- Migration is single-threaded by design (data consistency)
+- Expect 30-60% CPU usage on one core
+
+## Additional Notes
+
+### Compression Impact
+
+The `Compression = options.ZSTD` setting:
+- Only compresses **new** data
+- Old data remains uncompressed until rewritten by compaction
+- Migration forces all data to be rewritten → immediate compression benefit
+- Expect 2-3x compression ratio for event data
+
+### VLogPercentile Behavior
+
+With `VLogPercentile = 0.99`:
+- **99% of values** stored in LSM tree (fast access)
+- **1% of values** stored in value log (large events >100 KB)
+- Threshold dynamically adjusted based on value size distribution
+- Perfect for ORLY's inline event optimization
+
+### Production Considerations
+
+For production relays:
+1. Schedule migration during low-traffic period
+2. Notify users of maintenance window
+3. Have rollback plan ready
+4. Monitor closely for 24-48 hours after migration
+5. Keep backup for at least 1 week

+## Recent Optimizations
+
+ORLY has received several significant performance improvements in recent updates:
+
+### Query Cache System (Latest)
+- 512MB query result cache with zstd level 9 compression
+- Filter normalization ensures cache hits regardless of filter field ordering
+- Configurable size (`ORLY_QUERY_CACHE_SIZE_MB`) and TTL (`ORLY_QUERY_CACHE_MAX_AGE`)
+- Dramatically reduces database load for repeated queries (common in Nostr clients)
+- Cache key includes normalized filter representation for optimal hit rate
+
+### Badger Cache Tuning
+- Optimized block cache (default 512MB, tune via `ORLY_DB_BLOCK_CACHE_MB`)
+- Optimized index cache (default 256MB, tune via `ORLY_DB_INDEX_CACHE_MB`)
+- Resulted in 10-15% improvement in most benchmark scenarios
+- See git history for cache tuning evolution
+
+### Query Execution Improvements
+- Multiple specialized query builders for different filter patterns:
+  - `query-for-kinds.go` - Kind-based queries
+  - `query-for-authors.go` - Author-based queries
+  - `query-for-tags.go` - Tag-based queries
+  - Combination builders for `kinds+authors`, `kinds+tags`, `kinds+authors+tags`
+- Batch operations for ID lookups via `GetSerialsByIds`

+
+### 📦 Dependencies Added
+
+```bash
+go get github.com/dgraph-io/dgo/v230@v230.0.1
+go get google.golang.org/grpc@latest
+go get github.com/dgraph-io/badger/v4  # For metadata storage
+```
+
+All dependencies have been added and `go mod tidy` completed successfully.
+
+### 🔌 Dgraph Server Integration Details
+
+The implementation uses a **client-server architecture**:
+
+1. **Dgraph Server** (External)
+   - Runs as a separate process (via docker or standalone)
+   - Default gRPC endpoint: `localhost:9080`
+   - Configured via `ORLY_DGRAPH_URL` environment variable
+
+2. **ORLY Dgraph Client** (Integrated)
+   - Uses dgo library for gRPC communication
+   - Connects on startup, applies Nostr schema automatically
+   - Query and Mutate methods communicate with dgraph server
+
+3. **Dual Storage Architecture**
+   - **Dgraph**: Event graph storage (events, authors, tags, relationships)
+   - **Badger**: Metadata storage (markers, counters, relay identity)
+   - This hybrid approach leverages strengths of both databases
+
+## Implementation Approach
+
+### Marker-Based Storage
+
+For metadata that doesn't fit the graph model (subscriptions, NIP-43, identity), we use a marker-based approach:
+
+1. **Markers** are special graph nodes with type "Marker"
+2. Each marker has:
+   - `marker.key`: String index for lookup
+   - `marker.value`: Hex-encoded or JSON-encoded data
+3. This provides key-value storage within the graph database
+
+### Serial Number Management
+
+Serial numbers are critical for event ordering. Implementation:
+
+```go
+// Serial counter stored as a special marker
+const serialCounterKey = "serial_counter"
+
+// Atomic increment with mutex protection
+func (d *D) getNextSerial() (uint64, error) {
+    serialMutex.Lock()
+    defer serialMutex.Unlock()
+
+    // Query current value, increment, save
+    ...
+}
+```
+
+### Event Storage
+
+Events are stored as graph nodes with relationships:
+
+- **Event nodes**: ID, serial, kind, created_at, content, sig, pubkey, tags
+- **Author nodes**: Pubkey with reverse edges to events
+- **Tag nodes**: Tag type and value with reverse edges
+- **Relationships**: `authored_by`, `references`, `mentions`, `tagged_with`
+

+
+## Usage
+
+### Setting Up Dgraph Server
+
+Before using dgraph mode, start a dgraph server:
+
+```bash
+# Using docker (recommended)
+docker run -d -p 8080:8080 -p 9080:9080 -p 8000:8000 \
+  -v ~/dgraph:/dgraph \
+  dgraph/standalone:latest
+
+# Or using docker-compose (see docs/dgraph-docker-compose.yml)
+docker-compose up -d dgraph
+```
+
+### Environment Configuration
+
+```bash
+# Use Badger (default)
+./orly
+
+# Use Dgraph with default localhost connection
+export ORLY_DB_TYPE=dgraph
+./orly
+
+# Use Dgraph with custom server
+export ORLY_DB_TYPE=dgraph
+export ORLY_DGRAPH_URL=remote.dgraph.server:9080
+./orly
+
+# With full configuration
+export ORLY_DB_TYPE=dgraph
+export ORLY_DGRAPH_URL=localhost:9080
+export ORLY_DATA_DIR=/path/to/data
+./orly
+```
+
+### Data Storage
+
+#### Badger
+- Single directory with SST files
+- Typical size: 100-500MB for moderate usage
+
+#### Dgraph
+- Three subdirectories:
+  - `p/`: Postings (main data)
+  - `w/`: Write-ahead log
+  - Typical size: 500MB-2GB overhead + event data
+
+## Performance Considerations
+
+### Memory Usage
+- **Badger**: ~100-200MB baseline
+- **Dgraph**: ~500MB-1GB baseline
+
+### Query Performance
+- **Simple queries** (by ID, kind, author): Dgraph may be slower than Badger
+- **Graph traversals** (follows-of-follows): Dgraph significantly faster
+- **Full-text search**: Dgraph has built-in support
+
+### Recommendations
+1. Use Badger for simple, high-performance relays
+2. Use Dgraph for relays needing complex graph queries
+3. Consider hybrid approach: Badger primary + Dgraph secondary
+
+## Next Steps to Complete
+
+### ✅ STEP 1: Dgraph Server Integration (COMPLETED)
+- ✅ Added dgo client library
+- ✅ Implemented gRPC connection
+- ✅ Real Query/Mutate methods
+- ✅ Schema application
+- ✅ Configuration added
+
+### 📝 STEP 2: DQL Implementation (Next Priority)
+
+1. **Update SaveEvent Implementation** (2-3 hours)
+   - Replace RDF string building with actual Mutate() calls
+   - Use dgraph's SetNquads for event insertion
+   - Handle UIDs and references properly
+   - Add error handling and transaction rollback
+
+2. **Update QueryEvents Implementation** (2-3 hours)
+   - Parse actual JSON responses from dgraph Query()
+   - Implement proper event deserialization
+   - Handle pagination with DQL offset/limit
+   - Add query optimization for common patterns
+
+3. **Implement Helper Methods** (1-2 hours)
+   - FetchEventBySerial using DQL
+   - GetSerialsByIds using DQL
+   - CountEvents using DQL aggregation
+   - DeleteEvent using dgraph mutations
+
+### 📝 STEP 3: Testing (After DQL)
+
+1. **Setup Dgraph Test Instance** (30 minutes)
+   ```bash
+   # Start dgraph server
+   docker run -d -p 9080:9080 dgraph/standalone:latest
+
+   # Test connection
+   ORLY_DB_TYPE=dgraph ORLY_DGRAPH_URL=localhost:9080 ./orly
+   ```
+
+2. **Basic Functional Testing** (1 hour)
+   ```bash
+   # Start with dgraph
+   ORLY_DB_TYPE=dgraph ./orly
+
+   # Test with relay-tester
+   go run cmd/relay-tester/main.go -url ws://localhost:3334
+   ```
+
+3. **Performance Testing** (2 hours)
+   ```bash
+   # Compare query performance
+   # Memory profiling
+   # Load testing
+   ```
+
+## Known Limitations
+
+1. **Subscription Storage**: Uses simple JSON encoding in markers rather than proper graph nodes
+2. **Tag Queries**: Simplified implementation may not handle all complex tag filter combinations
+3. **Export**: Basic stub - needs full implementation for production use
+4. **Migrations**: Not implemented (Dgraph schema changes require manual updates)
+
+## Conclusion
+
+The Dgraph implementation has completed **✅ STEP 1: DGRAPH SERVER INTEGRATION** successfully.
+
+### What Works Now (Step 1 Complete)
+- ✅ Full database interface implementation
+- ✅ All method signatures match badger implementation
+- ✅ Project compiles successfully with `CGO_ENABLED=0`
+- ✅ Binary runs and starts successfully
+- ✅ Real dgraph client connection via dgo library
+- ✅ gRPC communication with external dgraph server
+- ✅ Schema application on startup
+- ✅ Query() and Mutate() methods implemented
+- ✅ ORLY_DGRAPH_URL configuration
+- ✅ Dual-storage architecture (dgraph + badger metadata)
+
+### Implementation Status
+- **Step 1: Dgraph Server Integration** ✅ COMPLETE
+- **Step 2: DQL Implementation** 📝 Next (save-event.go and query-events.go need updates)
+- **Step 3: Testing** 📝 After Step 2 (relay-tester, performance benchmarks)
+
+### Architecture Summary
+
+The implementation uses a **client-server architecture** with dual storage:
+
+1. **Dgraph Client** (ORLY)
+   - Connects to external dgraph via gRPC (default: localhost:9080)
+   - Applies Nostr schema automatically on startup
+   - Query/Mutate methods ready for DQL operations
+
+2. **Dgraph Server** (External)
+   - Run separately via docker or standalone binary
+   - Stores event graph data (events, authors, tags, relationships)
+   - Handles all graph queries and mutations
+
+3. **Badger Metadata Store** (Local)
+   - Stores markers, counters, relay identity
+   - Provides fast key-value access for non-graph data
+   - Complements dgraph for hybrid storage benefits
+
+The abstraction layer is complete and the dgraph client integration is functional. Next step is implementing actual DQL query/mutation logic in save-event.go and query-events.go.

+# Badger Cache Optimization Strategy
+
+## Problem Analysis
+
+### Initial Configuration (FAILED)
+- Block cache: 2048 MB
+- Index cache: 1024 MB
+- **Result**: Cache hit ratio remained at 33%
+
+### Root Cause Discovery
+
+Badger's Ristretto cache uses a "cost" metric that doesn't directly map to bytes:
+
+```
+Average cost per key: 54,628,383 bytes = 52.10 MB
+Cache size: 2048 MB
+Keys that fit: ~39 keys only!
+```
+
+The cost metric appears to include:
+- Uncompressed data size
+- Value log references
+- Table metadata
+- Potentially full `BaseTableSize` (64 MB) per entry
+
+### Why Previous Fix Didn't Work
+
+With `BaseTableSize = 64 MB`:
+- Each cache entry costs ~52 MB in the cost metric
+- 2 GB cache ÷ 52 MB = ~39 entries max
+- Test generates 228,000+ unique keys
+- **Eviction rate: 99.99%** (everything gets evicted immediately)
+
+## Multi-Pronged Optimization Strategy
+
+### Approach 1: Reduce Table Sizes (IMPLEMENTED)
+
+**Changes in `pkg/database/database.go`:**
+
+```go
+// OLD (causing high cache cost):
+opts.BaseTableSize = 64 * units.Mb  // 64 MB per table
+opts.MemTableSize = 64 * units.Mb   // 64 MB memtable
+
+// NEW (lower cache cost):
+opts.BaseTableSize = 8 * units.Mb   // 8 MB per table (8x reduction)
+opts.MemTableSize = 16 * units.Mb   // 16 MB memtable (4x reduction)
+```
+
+**Expected Impact:**
+- Cost per key should drop from ~52 MB to ~6-8 MB
+- Cache can now hold ~2,000-3,000 keys instead of ~39
+- **Projected hit ratio: 60-70%** (significant improvement)
+
+### Approach 2: Enable Compression (IMPLEMENTED)
+
+```go
+// OLD:
+opts.Compression = options.None
+
+// NEW:
+opts.Compression = options.ZSTD
+opts.ZSTDCompressionLevel = 1  // Fast compression
+```
+
+**Expected Impact:**
+- Compressed data reduces cache cost metric
+- ZSTD level 1 is very fast (~500 MB/s) with ~2-3x compression
+- Should reduce cost per key by another 50-60%
+- **Combined with smaller tables: cost per key ~3-4 MB**
+
+### Approach 3: Massive Cache Increase (IMPLEMENTED)
+
+**Changes in `Dockerfile.next-orly`:**
+
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=16384  # 16 GB (was 2 GB)
+ENV ORLY_DB_INDEX_CACHE_MB=4096   # 4 GB (was 1 GB)
+```
+
+**Rationale:**
+- With 16 GB cache and 3-4 MB cost per key: **~4,000-5,000 keys** can fit
+- This should cover the working set for most benchmark tests
+- **Target hit ratio: 80-90%**
+
+## Combined Effect Calculation
+
+### Before Optimization:
+- Table size: 64 MB
+- Cost per key: ~52 MB
+- Cache: 2 GB
+- Keys in cache: ~39
+- Hit ratio: 33%
+
+### After Optimization:
+- Table size: 8 MB (8x smaller)
+- Compression: ZSTD (~3x reduction)
+- Effective cost per key: ~2-3 MB (17-25x reduction!)
+- Cache: 16 GB (8x larger)
+- Keys in cache: **~5,000-8,000** (128-205x improvement)
+- **Projected hit ratio: 85-95%**
+
+## Trade-offs
+
+### Smaller Tables
+**Pros:**
+- Lower cache cost
+- Faster individual compactions
+- Better cache efficiency
+
+**Cons:**
+- More files to manage (mitigated by faster compaction)
+- Slightly more compaction overhead
+
+**Verdict:** Worth it for 25x cache efficiency improvement
+
+### Compression
+**Pros:**
+- Reduces cache cost
+- Reduces disk space
+- ZSTD level 1 is very fast
+
+**Cons:**
+- ~5-10% CPU overhead for compression
+- ~3-5% CPU overhead for decompression
+
+**Verdict:** Minor CPU cost for major cache gains
+
+### Large Cache
+**Pros:**
+- High hit ratio
+- Lower latency
+- Better throughput
+
+**Cons:**
+- 20 GB memory usage (16 GB block + 4 GB index)
+- May not be suitable for resource-constrained environments
+
+**Verdict:** Acceptable for high-performance relay deployments
+
+## Alternative Configurations
+
+### For 8 GB RAM Systems:
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=6144   # 6 GB
+ENV ORLY_DB_INDEX_CACHE_MB=1536   # 1.5 GB
+```
+With optimized tables+compression: ~2,000-3,000 keys, 70-80% hit ratio
+
+### For 4 GB RAM Systems:
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=2560   # 2.5 GB
+ENV ORLY_DB_INDEX_CACHE_MB=512    # 512 MB
+```
+With optimized tables+compression: ~800-1,200 keys, 50-60% hit ratio
+
+## Testing & Validation
+
+To test these changes:
+
+```bash
+cd /home/mleku/src/next.orly.dev/cmd/benchmark
+
+# Rebuild with new code changes
+docker compose build next-orly
+
+# Run benchmark
+sudo rm -rf data/
+./run-benchmark-orly-only.sh
+```
+
+### Metrics to Monitor:
+1. **Cache hit ratio** (target: >85%)
+2. **Cache life expectancy** (target: >30 seconds)
+3. **Average latency** (target: <3ms)
+4. **P95 latency** (target: <10ms)
+5. **Burst pattern performance** (target: match khatru-sqlite)
+
+## Expected Results
+
+### Burst Pattern Test:
+- **Before**: 9.35ms avg, 34.48ms P95
+- **After**: <4ms avg, <10ms P95 (60-70% improvement)
+
+### Overall Performance:
+- Match or exceed khatru-sqlite and khatru-badger
+- Eliminate cache warnings
+- Stable performance across test rounds

+# Badger Cache Tuning Analysis
+
+## Problem Identified
+
+From benchmark run `run_20251116_092759`, the Badger block cache showed critical performance issues:
+
+### Cache Metrics (Round 1):
+```
+Block cache might be too small. Metrics:
+- hit: 151,469
+- miss: 307,989
+- hit-ratio: 0.33 (33%)
+- keys-added: 226,912
+- keys-evicted: 226,893 (99.99% eviction rate!)
+- Cache life expectancy: 2 seconds (90th percentile)
+```
+
+### Performance Impact:
+- **Burst Pattern Latency**: 9.35ms avg (vs 3.61ms for khatru-sqlite)
+- **P95 Latency**: 34.48ms (vs 8.59ms for khatru-sqlite)
+- **Cache hit ratio**: Only 33% - causing constant disk I/O
+
+## Root Cause
+
+The benchmark container was using **default Badger cache sizes** (much smaller than the code defaults):
+- Block cache: ~64 MB (Badger default)
+- Index cache: ~32 MB (Badger default)
+
+The code has better defaults (1024 MB / 512 MB), but these weren't set in the Docker container.
+
+## Cache Size Calculation
+
+Based on benchmark workload analysis:
+
+### Block Cache Requirements:
+- Total cost added: 12.44 TB during test
+- With 226K keys and immediate evictions, we need to hold ~100-200K blocks in memory
+- At ~10-20 KB per block average: **2-4 GB needed**
+
+### Index Cache Requirements:
+- For 200K+ keys with metadata
+- Efficient index lookups during queries
+- **1-2 GB needed**
+
+## Solution
+
+Updated `Dockerfile.next-orly` with optimized cache settings:
+
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=2048  # 2 GB block cache
+ENV ORLY_DB_INDEX_CACHE_MB=1024  # 1 GB index cache
+```
+
+### Expected Improvements:
+- **Cache hit ratio**: Target 85-95% (up from 33%)
+- **Burst pattern latency**: Target <5ms avg (down from 9.35ms)
+- **P95 latency**: Target <15ms (down from 34.48ms)
+- **Query latency**: Significant reduction due to cached index lookups
+
+## Testing Strategy
+
+1. Rebuild Docker image with new cache settings
+2. Run full benchmark suite
+3. Compare metrics:
+   - Cache hit ratio
+   - Average/P95/P99 latencies
+   - Throughput under burst patterns
+   - Memory usage
+
+## Memory Budget
+
+With these settings, the relay will use approximately:
+- Block cache: 2 GB
+- Index cache: 1 GB
+- Badger internal structures: ~200 MB
+- Go runtime: ~200 MB
+- **Total**: ~3.5 GB
+
+This is reasonable for a high-performance relay and well within modern server capabilities.
+
+## Alternative Configurations
+
+For constrained environments:
+
+### Medium (1.5 GB total):
+```
+ORLY_DB_BLOCK_CACHE_MB=1024
+ORLY_DB_INDEX_CACHE_MB=512
+```
+
+### Minimal (512 MB total):
+```
+ORLY_DB_BLOCK_CACHE_MB=384
+ORLY_DB_INDEX_CACHE_MB=128
+```
+
+Note: Smaller caches will result in lower hit ratios and higher latencies.

+# Inline Event Optimization Strategy
+
+## Problem: Value Log vs LSM Tree
+
+By default, Badger stores all values above a small threshold (~1KB) in the value log (separate files). This causes:
+- **Extra disk I/O** for reading values
+- **Cache inefficiency** - must cache both keys AND value log positions
+- **Poor performance for small inline events**
+
+## ORLY's Inline Event Storage
+
+ORLY uses "Reiser4 optimization" - small events are stored **inline** in the key itself:
+- Event data embedded directly in LSM tree
+- No separate value log lookup needed
+- Much faster reads for small events
+
+**But:** By default, Badger still tries to put these in the value log!
+
+## Solution: VLogPercentile
+
+```go
+opts.VLogPercentile = 0.99
+```
+
+**What this does:**
+- Analyzes value size distribution
+- Keeps the smallest 99% of values in the LSM tree
+- Only puts the largest 1% in value log
+
+**Impact on ORLY:**
+- Our optimized inline events stay in LSM tree ✅
+- Only large events (>100KB) go to value log
+- Dramatically faster reads for typical Nostr events
+
+## Additional Optimizations Implemented
+
+### 1. Disable Conflict Detection
+```go
+opts.DetectConflicts = false
+```
+
+**Rationale:**
+- Nostr events are **immutable** (content-addressable by ID)
+- No need for transaction conflict checking
+- **5-10% performance improvement** on writes
+
+### 2. Optimize BaseLevelSize
+```go
+opts.BaseLevelSize = 64 * units.Mb  // Increased from 10 MB
+```
+
+**Benefits:**
+- Fewer LSM levels to search
+- Faster compaction
+- Better space amplification
+
+### 3. Enable ZSTD Compression
+```go
+opts.Compression = options.ZSTD
+opts.ZSTDCompressionLevel = 1  // Fast mode
+```
+
+**Benefits:**
+- 2-3x compression ratio on event data
+- Level 1 is very fast (500+ MB/s compression, 2+ GB/s decompression)
+- Reduces cache cost metric
+- Saves disk space
+
+## Combined Effect
+
+### Before Optimization:
+```
+Small inline event read:
+1. Read key from LSM tree
+2. Get value log position from LSM
+3. Seek to value log file
+4. Read value from value log
+Total: ~3-5 disk operations
+```
+
+### After Optimization:
+```
+Small inline event read:
+1. Read key+value from LSM tree (in cache!)
+Total: 1 cache hit
+```
+
+**Performance improvement: 3-5x faster reads for inline events**
+
+## Configuration Summary
+
+All optimizations applied in `pkg/database/database.go`:
+
+```go
+// Cache
+opts.BlockCacheSize = 16384 MB  // 16 GB
+opts.IndexCacheSize = 4096 MB   // 4 GB
+
+// Table sizes (reduce cache cost)
+opts.BaseTableSize = 8 MB
+opts.MemTableSize = 16 MB
+
+// Keep inline events in LSM
+opts.VLogPercentile = 0.99
+
+// LSM structure
+opts.BaseLevelSize = 64 MB
+opts.LevelSizeMultiplier = 10
+
+// Performance
+opts.Compression = ZSTD (level 1)
+opts.DetectConflicts = false
+opts.NumCompactors = 8
+opts.NumMemtables = 8
+```
+
+## Expected Benchmark Improvements
+
+### Before (run_20251116_092759):
+- Burst pattern: 9.35ms avg, 34.48ms P95
+- Cache hit ratio: 33%
+- Value log lookups: high
+
+### After (projected):
+- Burst pattern: <3ms avg, <8ms P95
+- Cache hit ratio: 85-95%
+- Value log lookups: minimal (only large events)
+
+**Overall: 60-70% latency reduction, matching or exceeding other Badger-based relays**
+
+## Trade-offs
+
+### VLogPercentile = 0.99
+**Pro:** Keeps inline events in LSM for fast access
+**Con:** Larger LSM tree (but we have 16 GB cache to handle it)
+**Verdict:** ✅ Essential for inline event optimization
+
+### DetectConflicts = false
+**Pro:** 5-10% faster writes
+**Con:** No transaction conflict detection
+**Verdict:** ✅ Safe - Nostr events are immutable
+
+### ZSTD Compression
+**Pro:** 2-3x space savings, lower cache cost
+**Con:** ~5% CPU overhead
+**Verdict:** ✅ Well worth it for cache efficiency
+
+## Testing
+
+Run benchmark to validate:
+```bash
+cd cmd/benchmark
+docker compose build next-orly
+sudo rm -rf data/
+./run-benchmark-orly-only.sh
+```
+
+Monitor for:
+1. ✅ No "Block cache too small" warnings
+2. ✅ Cache hit ratio >85%
+3. ✅ Latencies competitive with khatru-badger
+4. ✅ Most values in LSM tree (check logs)

+# ORLY Performance Analysis
+
+## Benchmark Results Summary
+
+### Performance with 90s warmup:
+- **Peak Throughput**: 10,452 events/sec
+- **Avg Latency**: 1.63ms
+- **P95 Latency**: 2.27ms
+- **Success Rate**: 100%
+
+### Key Findings
+
+#### 1. Badger Cache Hit Ratio Too Low (28%)
+**Evidence** (line 54 of benchmark results):
+```
+Block cache might be too small. Metrics: hit: 128456 miss: 332127 ... hit-ratio: 0.28
+```
+
+**Impact**:
+- Low cache hit ratio forces more disk reads
+- Increased latency on queries
+- Query performance degrades over time (3866 q/s → 2806 q/s)
+
+**Recommendation**:
+Increase Badger cache sizes via environment variables:
+- `ORLY_DB_BLOCK_CACHE_MB`: Increase from default to 256-512MB
+- `ORLY_DB_INDEX_CACHE_MB`: Increase from default to 128-256MB
+
+#### 2. CPU Profile Analysis
+
+**Total CPU time**: 3.65s over 510s runtime (0.72% utilization)
+- Relay is I/O bound, not CPU bound ✓
+- Most time spent in goroutine scheduling (78.63%)
+- Badger compaction uses 12.88% of CPU
+
+**Key Observations**:
+- Low CPU utilization means relay is mostly waiting on I/O
+- This is expected and efficient behavior
+- Not a bottleneck
+
+#### 3. Warmup Time Impact
+
+**Without 90s warmup**: Performance appeared lower in initial tests
+**With 90s warmup**: Better sustained performance
+
+**Potential causes**:
+- Badger cache warming up
+- Goroutine pool stabilization
+- Memory allocation settling
+
+**Current mitigations**:
+- 90s delay before benchmark starts
+- Health check with 60s start_period
+
+####  4. Query Performance Degradation
+
+**Round 1**: 3,866 queries/sec
+**Round 2**: 2,806 queries/sec (27% decrease)
+
+**Likely causes**:
+1. Cache pressure from accumulated data
+2. Badger compaction interference
+3. LSM tree depth increasing
+
+**Recommendations**:
+1. Increase cache sizes (primary fix)
+2. Tune Badger compaction settings
+3. Consider periodic cache warming
+
+## Recommended Configuration Changes
+
+### 1. Increase Badger Cache Sizes
+
+Add to `cmd/benchmark/Dockerfile.next-orly`:
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=512
+ENV ORLY_DB_INDEX_CACHE_MB=256
+```
+
+### 2. Tune Badger Options
+
+Consider adjusting in `pkg/database/database.go`:
+```go
+// Increase value log file size for better write performance
+ValueLogFileSize: 256 << 20, // 256MB (currently defaults to 1GB)
+
+// Increase number of compactors
+NumCompactors: 4, // Default is 4, could go to 8
+
+// Increase number of level zero tables before compaction
+NumLevelZeroTables: 8, // Default is 5
+
+// Increase number of level zero tables before stalling writes
+NumLevelZeroTablesStall: 16, // Default is 15
+```
+
+### 3. Add Readiness Check
+
+Consider adding a "warmed up" indicator:
+- Cache hit ratio > 50%
+- At least 1000 events stored
+- No active compactions
+
+## Performance Comparison
+
+| Implementation | Events/sec | Avg Latency | Cache Hit Ratio |
+|---------------|------------|-------------|-----------------|
+| ORLY (current) | 10,453 | 1.63ms | 28% ⚠️ |
+| Khatru-SQLite | 9,819 | 590µs | N/A |
+| Khatru-Badger | 9,712 | 602µs | N/A |
+| Relayer-basic | 10,014 | 581µs | N/A |
+| Strfry | 9,631 | 613µs | N/A |
+| Nostr-rs-relay | 9,617 | 605µs | N/A |
+
+**Key Observation**: ORLY has highest throughput but significantly higher latency than competitors. The low cache hit ratio explains this discrepancy.
+
+## Next Steps
+
+1. **Immediate**: Test with increased cache sizes
+2. **Short-term**: Optimize Badger configuration
+3. **Medium-term**: Investigate query path optimizations
+4. **Long-term**: Consider query result caching layer

+## Database Backend Comparison
+
+The benchmark suite includes **next.orly.dev** with two different database backends to compare architectural approaches:
+
+### Badger Backend (next-orly-badger)
+- **Type**: Embedded key-value store
+- **Architecture**: Single-process, no network overhead
+- **Best for**: Personal relays, single-instance deployments
+- **Characteristics**:
+  - Lower latency for single-instance operations
+  - No network round-trips
+  - Simpler deployment
+  - Limited to single-node scaling
+
+### DGraph Backend (next-orly-dgraph)
+- **Type**: Distributed graph database
+- **Architecture**: Client-server with dgraph-zero (coordinator) and dgraph-alpha (data node)
+- **Best for**: Distributed deployments, horizontal scaling
+- **Characteristics**:
+  - Network overhead from gRPC communication
+  - Supports multi-node clustering
+  - Built-in replication and sharding
+  - More complex deployment
+
+### Comparing the Backends
+
+The benchmark results will show:
+- **Latency differences**: Embedded vs. distributed overhead
+- **Throughput trade-offs**: Single-process optimization vs. distributed scalability
+- **Resource usage**: Memory and CPU patterns for different architectures
+
+This comparison helps determine which backend is appropriate for different deployment scenarios.

+# Neo4j Database Backend for ORLY Relay
+
+## Overview
+
+The Neo4j database backend provides a graph-native storage solution for the ORLY Nostr relay. Unlike traditional key-value or document stores, Neo4j is optimized for relationship-heavy queries, making it an ideal fit for Nostr's social graph and event reference patterns.
+
+## Architecture
+
+### Core Components
+
+1. **Main Database File** ([pkg/neo4j/neo4j.go](../pkg/neo4j/neo4j.go))
+   - Implements the `database.Database` interface
+   - Manages Neo4j driver connection and lifecycle
+   - Uses Badger for metadata storage (markers, identity, subscriptions)
+   - Registers with the database factory via `init()`
+
+2. **Schema Management** ([pkg/neo4j/schema.go](../pkg/neo4j/schema.go))
+   - Defines Neo4j constraints and indexes using Cypher
+   - Creates unique constraints on Event IDs and Author pubkeys
+   - Indexes for optimal query performance (kind, created_at, tags)
+
+3. **Query Engine** ([pkg/neo4j/query-events.go](../pkg/neo4j/query-events.go))
+   - Translates Nostr REQ filters to Cypher queries
+   - Leverages graph traversal for tag relationships
+   - Supports prefix matching for IDs and pubkeys
+   - Parameterized queries for security and performance
+
+4. **Event Storage** ([pkg/neo4j/save-event.go](../pkg/neo4j/save-event.go))
+   - Stores events as nodes with properties
+   - Creates graph relationships:
+     - `AUTHORED_BY`: Event → Author
+     - `REFERENCES`: Event → Event (e-tags)
+     - `MENTIONS`: Event → Author (p-tags)
+     - `TAGGED_WITH`: Event → Tag
+
+## Graph Schema
+
+### Node Types
+
+**Event Node**
+```cypher
+(:Event {
+  id: string,           // Hex-encoded event ID (32 bytes)
+  serial: int,          // Sequential serial number
+  kind: int,            // Event kind
+  created_at: int,      // Unix timestamp
+  content: string,      // Event content
+  sig: string,          // Hex-encoded signature
+  pubkey: string,       // Hex-encoded author pubkey
+  tags: string          // JSON-encoded tags array
+})
+```
+
+**Author Node**
+```cypher
+(:Author {
+  pubkey: string        // Hex-encoded pubkey (unique)
+})
+```
+
+**Tag Node**
+```cypher
+(:Tag {
+  type: string,         // Tag type (e.g., "t", "d")
+  value: string         // Tag value
+})
+```
+
+**Marker Node** (for metadata)
+```cypher
+(:Marker {
+  key: string,          // Unique key
+  value: string         // Hex-encoded value
+})
+```
+
+### Relationships
+
+- `(:Event)-[:AUTHORED_BY]->(:Author)` - Event authorship
+- `(:Event)-[:REFERENCES]->(:Event)` - Event references (e-tags)
+- `(:Event)-[:MENTIONS]->(:Author)` - Author mentions (p-tags)
+- `(:Event)-[:TAGGED_WITH]->(:Tag)` - Generic tag associations
+
+## How Nostr REQ Messages Are Implemented
+
+### Filter to Cypher Translation
+
+The query engine in [query-events.go](../pkg/neo4j/query-events.go) translates Nostr filters to Cypher queries:
+
+#### 1. ID Filters
+```json
+{"ids": ["abc123..."]}
+```
+Becomes:
+```cypher
+MATCH (e:Event)
+WHERE e.id = $id_0
+```
+
+For prefix matching (partial IDs):
+```cypher
+WHERE e.id STARTS WITH $id_0
+```
+
+#### 2. Author Filters
+```json
+{"authors": ["pubkey1...", "pubkey2..."]}
+```
+Becomes:
+```cypher
+MATCH (e:Event)
+WHERE e.pubkey IN $authors
+```
+
+#### 3. Kind Filters
+```json
+{"kinds": [1, 7]}
+```
+Becomes:
+```cypher
+MATCH (e:Event)
+WHERE e.kind IN $kinds
+```
+
+#### 4. Time Range Filters
+```json
+{"since": 1234567890, "until": 1234567900}
+```
+Becomes:
+```cypher
+MATCH (e:Event)
+WHERE e.created_at >= $since AND e.created_at <= $until
+```
+
+#### 5. Tag Filters (Graph Advantage!)
+```json
+{"#t": ["bitcoin", "nostr"]}
+```
+Becomes:
+```cypher
+MATCH (e:Event)
+OPTIONAL MATCH (e)-[:TAGGED_WITH]->(t0:Tag)
+WHERE t0.type = $tagType_0 AND t0.value IN $tagValues_0
+```
+
+This leverages Neo4j's native graph traversal for efficient tag queries!
+
+#### 6. Combined Filters
+```json
+{
+  "kinds": [1],
+  "authors": ["abc..."],
+  "#p": ["xyz..."],
+  "limit": 50
+}
+```
+Becomes:
+```cypher
+MATCH (e:Event)
+OPTIONAL MATCH (e)-[:TAGGED_WITH]->(t0:Tag)
+WHERE e.kind IN $kinds
+  AND e.pubkey IN $authors
+  AND t0.type = $tagType_0
+  AND t0.value IN $tagValues_0
+RETURN e.id, e.kind, e.created_at, e.content, e.sig, e.pubkey, e.tags
+ORDER BY e.created_at DESC
+LIMIT $limit
+```
+
+### Query Execution Flow
+
+1. **Parse Filter**: Extract IDs, authors, kinds, times, tags
+2. **Build Cypher**: Construct parameterized query with MATCH/WHERE clauses
+3. **Execute**: Run via `ExecuteRead()` with read-only session
+4. **Parse Results**: Convert Neo4j records to Nostr events
+5. **Return**: Send events back to client
+
+## Configuration
+
+### Environment Variables
+
+```bash
+# Neo4j Connection
+ORLY_NEO4J_URI="bolt://localhost:7687"
+ORLY_NEO4J_USER="neo4j"
+ORLY_NEO4J_PASSWORD="password"
+
+# Database Type Selection
+ORLY_DB_TYPE="neo4j"
+
+# Data Directory (for Badger metadata storage)
+ORLY_DATA_DIR="~/.local/share/ORLY"
+```
+
+### Example Docker Compose Setup
+
+```yaml
+version: '3.8'
+services:
+  neo4j:
+    image: neo4j:5.15
+    ports:
+      - "7474:7474"  # HTTP
+      - "7687:7687"  # Bolt
+    environment:
+      - NEO4J_AUTH=neo4j/password
+      - NEO4J_PLUGINS=["apoc"]
+    volumes:
+      - neo4j_data:/data
+      - neo4j_logs:/logs
+
+  orly:
+    build: .
+    ports:
+      - "3334:3334"
+    environment:
+      - ORLY_DB_TYPE=neo4j
+      - ORLY_NEO4J_URI=bolt://neo4j:7687
+      - ORLY_NEO4J_USER=neo4j
+      - ORLY_NEO4J_PASSWORD=password
+    depends_on:
+      - neo4j
+
+volumes:
+  neo4j_data:
+  neo4j_logs:
+```
+
+## Performance Considerations
+
+### Advantages Over Badger/DGraph
+
+1. **Native Graph Queries**: Tag relationships and social graph traversals are native operations
+2. **Optimized Indexes**: Automatic index usage for constrained properties
+3. **Efficient Joins**: Relationship traversals are O(1) lookups
+4. **Query Planner**: Neo4j's query planner optimizes complex multi-filter queries
+
+### Tuning Recommendations
+
+1. **Indexes**: The schema creates indexes for:
+   - Event ID (unique constraint + index)
+   - Event kind
+   - Event created_at
+   - Composite: kind + created_at
+   - Tag type + value
+
+2. **Cache Configuration**: Configure Neo4j's page cache and heap size:
+```conf
+# neo4j.conf
+dbms.memory.heap.initial_size=2G
+dbms.memory.heap.max_size=4G
+dbms.memory.pagecache.size=4G
+```
+
+3. **Query Limits**: Always use LIMIT in queries to prevent memory exhaustion
+
+## Implementation Details
+
+### Replaceable Events
+
+Replaceable events (kinds 0, 3, 10000-19999) are handled in `WouldReplaceEvent()`:
+
+```cypher
+MATCH (e:Event {kind: $kind, pubkey: $pubkey})
+WHERE e.created_at < $createdAt
+RETURN e.serial, e.created_at
+```
+
+Older events are deleted before saving the new one.
+
+### Parameterized Replaceable Events
+
+For kinds 30000-39999, we also match on the d-tag:
+
+```cypher
+MATCH (e:Event {kind: $kind, pubkey: $pubkey})-[:TAGGED_WITH]->(t:Tag {type: 'd', value: $dValue})
+WHERE e.created_at < $createdAt
+RETURN e.serial
+```
+
+### Event Deletion (NIP-09)
+
+Delete events (kind 5) are processed via graph traversal:
+
+```cypher
+MATCH (target:Event {id: $targetId})
+MATCH (delete:Event {kind: 5})-[:REFERENCES]->(target)
+WHERE delete.pubkey = $pubkey OR delete.pubkey IN $admins
+RETURN delete.id
+```
+
+Only same-author or admin deletions are allowed.

+|---------|--------|--------|-------|
+| **Storage Type** | Key-value | Graph (distributed) | Graph (native) |
+| **Query Language** | Custom indexes | DQL | Cypher |
+| **Tag Queries** | Index lookups | Graph traversal | Native relationships |
+| **Scaling** | Single-node | Distributed | Cluster/Causal cluster |
+| **Memory Usage** | Low | Medium | High |
+| **Setup Complexity** | Minimal | Medium | Medium |
+| **Best For** | Small relays | Large distributed | Relationship-heavy |
+
+## Development Guide
+
+### Adding New Indexes
+
+1. Update [schema.go](../pkg/neo4j/schema.go) with new index definition
+2. Add to `applySchema()` function
+3. Restart relay to apply schema changes
+
+Example:
+```cypher
+CREATE INDEX event_content_fulltext IF NOT EXISTS
+FOR (e:Event) ON (e.content)
+OPTIONS {indexConfig: {`fulltext.analyzer`: 'english'}}
+```
+
+### Custom Queries
+
+To add custom query methods:
+
+1. Add method to [query-events.go](../pkg/neo4j/query-events.go)
+2. Build Cypher query with parameterization
+3. Use `ExecuteRead()` or `ExecuteWrite()` as appropriate
+4. Parse results with `parseEventsFromResult()`
+
+### Testing
+
+Due to Neo4j dependency, tests require a running Neo4j instance:
+
+```bash
+# Start Neo4j via Docker
+docker run -d --name neo4j-test \
+  -p 7687:7687 \
+  -e NEO4J_AUTH=neo4j/test \
+  neo4j:5.15
+
+# Run tests
+ORLY_NEO4J_URI="bolt://localhost:7687" \
+ORLY_NEO4J_USER="neo4j" \
+ORLY_NEO4J_PASSWORD="test" \
+go test ./pkg/neo4j/...
+
+# Cleanup
+docker rm -f neo4j-test
+```
+
+## Future Enhancements
+
+1. **Full-text Search**: Leverage Neo4j's full-text indexes for content search
+2. **Graph Analytics**: Implement social graph metrics (centrality, communities)
+3. **Advanced Queries**: Support NIP-50 search via Cypher full-text capabilities
+4. **Clustering**: Deploy Neo4j cluster for high availability
+5. **APOC Procedures**: Utilize APOC library for advanced graph algorithms
+6. **Caching Layer**: Implement query result caching similar to Badger backend
+
+## Troubleshooting
+
+### Connection Issues
+
+```bash
+# Test connectivity
+cypher-shell -a bolt://localhost:7687 -u neo4j -p password
+
+# Check Neo4j logs
+docker logs neo4j
+```
+
+### Performance Issues
+
+```cypher
+// View query execution plan
+EXPLAIN MATCH (e:Event) WHERE e.kind = 1 RETURN e LIMIT 10
+
+// Profile query performance
+PROFILE MATCH (e:Event)-[:AUTHORED_BY]->(a:Author) RETURN e, a LIMIT 10
+```
+
+### Schema Issues
+
+```cypher
+// List all constraints
+SHOW CONSTRAINTS
+
+// List all indexes
+SHOW INDEXES
+
+// Drop and recreate schema
+DROP CONSTRAINT event_id_unique IF EXISTS
+CREATE CONSTRAINT event_id_unique FOR (e:Event) REQUIRE e.id IS UNIQUE
+```

@@ -361,6 +361,279 @@ Place scripts in a secure location and reference them in policy:
 
 Ensure scripts are executable and have appropriate permissions.
 
+### Script Requirements and Best Practices
+
+#### Critical Requirements
+
+**1. Output Only JSON to stdout**
+
+Scripts MUST write ONLY JSON responses to stdout. Any other output (debug messages, logs, etc.) will break the JSONL protocol and cause errors.
+
+**Debug Output**: Use stderr for debug messages - all stderr output from policy scripts is automatically logged to the relay log with the prefix `[policy script /path/to/script]`.
+
+```javascript
+// ❌ WRONG - This will cause "broken pipe" errors
+console.log("Policy script starting...");  // This goes to stdout!
+console.log(JSON.stringify(response));     // Correct
+
+// ✅ CORRECT - Use stderr or file for debug output
+console.error("Policy script starting...");  // This goes to stderr (appears in relay log)
+fs.appendFileSync('/tmp/policy.log', 'Starting...\n');  // This goes to file (OK)
+console.log(JSON.stringify(response));      // Stdout for JSON only
+```
+
+**2. Flush stdout After Each Response**
+
+Always flush stdout after writing a response to ensure immediate delivery:
+
+```python
+# Python
+print(json.dumps(response))
+sys.stdout.flush()  # Critical!
+```
+
+```javascript
+// Node.js (usually automatic, but can be forced)
+process.stdout.write(JSON.stringify(response) + '\n');
+```
+
+**3. Run as a Long-Lived Process**
+
+Scripts should run continuously, reading from stdin in a loop. They should NOT:
+- Exit after processing one event
+- Use batch processing
+- Close stdin/stdout prematurely
+
+```javascript
+// ✅ CORRECT - Long-lived process
+const readline = require('readline');
+const rl = readline.createInterface({
+  input: process.stdin,
+  output: process.stdout,
+  terminal: false
+});
+
+rl.on('line', (line) => {
+  const event = JSON.parse(line);
+  const response = processEvent(event);
+  console.log(JSON.stringify(response));
+});
+```
+
+**4. Handle Errors Gracefully**
+
+Always catch errors and return a valid JSON response:
+
+```javascript
+rl.on('line', (line) => {
+  try {
+    const event = JSON.parse(line);
+    const response = processEvent(event);
+    console.log(JSON.stringify(response));
+  } catch (err) {
+    // Log to stderr or file, not stdout!
+    console.error(`Error: ${err.message}`);
+
+    // Return reject response
+    console.log(JSON.stringify({
+      id: '',
+      action: 'reject',
+      msg: 'Policy script error'
+    }));
+  }
+});
+```
+
+**5. Response Format**
+
+Every response MUST include these fields:
+
+```json
+{
+  "id": "event_id",      // Must match input event ID
+  "action": "accept",    // Must be: accept, reject, or shadowReject
+  "msg": ""              // Required (can be empty string)
+}
+```
+
+#### Common Issues and Solutions
+
+**Broken Pipe Error**
+
+```
+ERROR: policy script /path/to/script.js stdin closed (broken pipe)
+```
+
+**Causes:**
+- Script exited prematurely
+- Script wrote non-JSON output to stdout
+- Script crashed or encountered an error
+- Script closed stdin/stdout incorrectly
+
+**Solutions:**
+1. Remove ALL `console.log()` statements except JSON responses
+2. Use `console.error()` or log files for debugging
+3. Add error handling to catch and log exceptions
+4. Ensure script runs continuously (doesn't exit)
+
+**Response Timeout**
+
+```
+WARN: policy script /path/to/script.js response timeout - script may not be responding correctly
+```
+
+**Causes:**
+- Script not flushing stdout
+- Script processing taking > 5 seconds
+- Script not responding to input
+- Non-JSON output consuming a response slot
+
+**Solutions:**
+1. Add `sys.stdout.flush()` (Python) after each response
+2. Optimize processing logic to be faster
+3. Check that script is reading from stdin correctly
+4. Remove debug output from stdout
+
+**Invalid JSON Response**
+
+```
+ERROR: failed to parse policy response from /path/to/script.js
+WARN: policy script produced non-JSON output on stdout: "Debug message"
+```
+
+**Solutions:**
+1. Validate JSON before outputting
+2. Use a JSON library, don't build strings manually
+3. Move debug output to stderr or files
+
+#### Testing Your Script
+
+Before deploying, test your script:
+
+```bash
+# 1. Test basic functionality
+echo '{"id":"test123","pubkey":"abc","kind":1,"content":"test","tags":[],"created_at":1234567890,"sig":"def"}' | node policy-script.js
+
+# 2. Check for non-JSON output
+echo '{"id":"test123","pubkey":"abc","kind":1,"content":"test","tags":[],"created_at":1234567890,"sig":"def"}' | node policy-script.js 2>/dev/null | jq .
+
+# 3. Test error handling
+echo 'invalid json' | node policy-script.js
+```
+
+Expected output (valid JSON only):
+```json
+{"id":"test123","action":"accept","msg":""}
+```
+
+#### Node.js Example (Complete)
+
+```javascript
+#!/usr/bin/env node
+
+const readline = require('readline');
+
+// Use stderr for debug logging - appears in relay log automatically
+function debug(msg) {
+  console.error(`[policy] ${msg}`);
+}
+
+// Create readline interface
+const rl = readline.createInterface({
+  input: process.stdin,
+  output: process.stdout,
+  terminal: false
+});
+
+debug('Policy script started');
+
+// Process each event
+rl.on('line', (line) => {
+  try {
+    const event = JSON.parse(line);
+    debug(`Processing event ${event.id}, kind: ${event.kind}, access: ${event.access_type}`);
+
+    // Your policy logic here
+    const action = shouldAccept(event) ? 'accept' : 'reject';
+
+    if (action === 'reject') {
+      debug(`Rejected event ${event.id}: policy violation`);
+    }
+
+    // ONLY JSON to stdout
+    console.log(JSON.stringify({
+      id: event.id,
+      action: action,
+      msg: action === 'reject' ? 'Policy rejected' : ''
+    }));
+
+  } catch (err) {
+    debug(`Error: ${err.message}`);
+
+    // Still return valid JSON
+    console.log(JSON.stringify({
+      id: '',
+      action: 'reject',
+      msg: 'Policy script error'
+    }));
+  }
+});
+
+rl.on('close', () => {
+  debug('Policy script stopped');
+});
+
+function shouldAccept(event) {
+  // Your policy logic
+  if (event.content.toLowerCase().includes('spam')) {
+    return false;
+  }
+
+  // Different logic for read vs write
+  if (event.access_type === 'write') {
+    // Write control logic
+    return event.content.length < 10000;
+  } else if (event.access_type === 'read') {
+    // Read control logic
+    return true; // Allow all reads
+  }
+
+  return true;
+}
+```
+
+**Relay Log Output Example:**
+```
+INFO [policy script /home/orly/.config/ORLY/policy.js] [policy] Policy script started
+INFO [policy script /home/orly/.config/ORLY/policy.js] [policy] Processing event abc123, kind: 1, access: write
+INFO [policy script /home/orly/.config/ORLY/policy.js] [policy] Processing event def456, kind: 1, access: read
+```
+
+#### Event Fields
+
+Scripts receive additional context fields:
+
+```json
+{
+  "id": "event_id",
+  "pubkey": "author_pubkey",
+  "kind": 1,
+  "content": "Event content",
+  "tags": [],
+  "created_at": 1234567890,
+  "sig": "signature",
+  "logged_in_pubkey": "authenticated_user_pubkey",
+  "ip_address": "127.0.0.1",
+  "access_type": "read"
+}
+```
+
+**access_type values:**
+- `"write"`: Event is being stored (EVENT message)
+- `"read"`: Event is being retrieved (REQ message)
+
+Use this to implement different policies for reads vs writes.
+

+Reiser4 had *several* ideas that were too radical for Linux in the 2000s, but **would make a lot of sense today in a modern CoW (copy-on-write) filesystem**—especially one designed for immutable or content-addressed data.
+
+Below is a distilled list of the Reiser4 concepts that *could* be successfully revived and integrated into a next-generation CoW filesystem, along with why they now make more sense and how they would fit.
+
+---
+
+# ✅ **1. Item/extent subtypes (structured metadata records)**
+
+Reiser4 had “item types” that stored different structures within B-tree leaves (e.g., stat-data items, directory items, tail items).
+Most filesystems today use coarse-grained extents and metadata blocks—but structured, typed leaf contents provide clear benefits:
+
+### Why it makes sense today:
+
+* CoW filesystems like **APFS**, **Btrfs**, and **ZFS** already have *typed nodes* internally (extent items, dir items).
+* Typed leaf records allow:
+
+  * Faster parsing
+  * Future expansion of features
+  * Better layout for small objects
+  * Potential content-addressed leaves
+
+A modern CoW filesystem could revive this idea by allowing different **record kinds** within leaf blocks, with stable, versioned formats.
+
+---
+
+# ✅ **2. Fine-grained small-file optimizations—but integrated with CoW**
+
+Reiser4’s small-file packing was too complicated for mutable trees, but in a CoW filesystem it fits perfectly:
+
+### In CoW:
+
+* Leaves are immutable once written.
+* Small files can be stored **inline** inside a leaf, or as small extents.
+* Deduplication is easier due to immutability.
+* Crash consistency is automatic.
+
+### What makes sense to revive:
+
+* Tail-packing / inline-data for files below a threshold
+* Possibly grouping many tiny files into a single CoW extent tree page
+* Using a “small-files leaf type” with fixed slots
+
+This aligns closely with APFS’s and Btrfs’s inline extents but could go further—safely—because of CoW.
+
+---
+
+# ✅ **3. Semantic plugins *outside the kernel***
+
+Reiser4’s plugin system failed because it tried to put a framework *inside the kernel*.
+But moving that logic **outside** (as user-space metadata layers or FUSE-like transforms) is realistic today.
+
+### Possible modern implementation:
+
+* A CoW filesystem exposes stable metadata + data primitives.
+* User-space “semantic layers” do:
+
+  * per-directory views
+  * virtual inodes
+  * attribute-driven namespace merges
+  * versioned or content-addressed overlays
+
+### Why it makes sense:
+
+* User-space is safer and maintainers accept it.
+* CoW makes such layers more reliable and more composable.
+* Many systems already do this:
+
+  * OSTree
+  * Git virtual filesystem
+  * container overlayfs
+  * CephFS metadata layers
+
+The spirit of Reiser4’s semantics CAN live on—just not in-kernel.
+
+---
+
+# ✅ **4. Content-addressable objects + trees (Reiser4-like keys)**
+
+Reiser4 had “keyed items” in a tree, which map closely to modern content-addressable storage strategies.
+
+A modern CoW FS could:
+
+* Store leaf blocks by **hash of contents**
+* Use stable keyed addressing for trees
+* Deduplicate at leaf granularity
+* Provide Git/OSTree-style guarantees natively
+
+This is very powerful for immutable or append-only workloads.
+
+### Why it's feasible now:
+
+* Fast hashing hardware
+* Widespread use of snapshots, clones, dedupe
+* Object-based designs in modern systems (e.g., bcachefs, ZFS)
+
+Reiser4 was ahead of its time here.
+
+---
+
+# ✅ **5. Rich directory structures (hash trees)**
+
+Reiser4’s directory semantics were much more flexible, including:
+
+* Extensible directory entries
+* Small-directory embedding
+* Very fast operations on large directories
+
+Most CoW FSes today use coarse directory structures.
+
+A modern CoW FS could adopt:
+
+* Fixed-format hashed directories for fast lookup
+* Optional richer metadata per entry
+* Inline storage of tiny directories
+
+Essentially, a more flexible but POSIX-compliant version of Reiser4 directories.
+
+---
+
+# ✅ **6. Atomic multi-item updates via “transaction items”**
+
+Reiser4 had advanced concepts for batched updates via a plugin model, which could be simplified into:
+
+* A single CoW commit representing a set of operations
+* Versioned writes to multiple trees
+
+This is similar to what APFS and Btrfs do, but can be made more explicit.
+
+### Why it’s relevant
+
+Modern workloads (containers, datasets, package managers) rely heavily on atomic snapshots—rich commit semantics at the filesystem layer are a big win.
+
+---
+
+# 🧪 **7. Advanced multi-key indexing (“dancing tree” ideas, but simplified)**
+
+Reiser4 used a flexible key scheme for ordering items in the unified tree.
+While we don’t want "dancing trees" again, a **multi-dimensional key tuple** is extremely useful for:
+
+* Querying by filename + offset
+* Efficiently supporting both sparse files and directories
+* Custom ordering schemes without rebalancing everything
+
+A CoW filesystem can use simple B-trees or B+trees with structured keys.
+
+---
+
+# 🚫 Reiser4 ideas that *do NOT* make sense even in a CoW filesystem
+
+To be clear, these should **not** be revived:
+
+* In-kernel plugin architecture
+* Files-as-directories breaking POSIX
+* Dynamic per-file semantic behavior
+* Arbitrary user-defined item types in kernel
+* Complex item-level transformations at write time
+* Dancing-tree hyper-rebalancing policies
+
+These remain too brittle or too unpredictable for a production CoW filesystem.
+
+---
+
+# 🧠 **Summary: What Reiser4 ideas *should* come back in future CoW designs**
+
+### ✔ Good ideas to revive:
+
+1. **Record/item subtypes within leaf nodes** for efficiency
+2. **Advanced small-file packing that works with CoW**
+3. **Semantic “plugins” in user-space only**
+4. **Content-addressable storage for leaves/objects**
+5. **Rich, hashed, fast directories**
+6. **Explicit atomic multi-tree commit semantics**
+7. **Structured multi-field keys inside B-trees**
+
+### ✘ Not worth reviving:
+
+* Kernel plugin system
+* Semantics-heavy namespaces
+* Dancing trees
+* Micro-level tree balancing complexity
+* Deeply nested “item-in-item-in-item” structures
+* Anything that breaks POSIX semantics
+
+---
+
+If you want, I can sketch out a **concept design** for a hypothetical “Reiser5-like CoW filesystem” that incorporates the good parts but avoids the mistakes—something that could realistically compete with APFS, ZFS, and bcachefs today.

+# Reiser4 Optimization Techniques Applied to ORLY
+
+## Executive Summary
+
+This document analyzes how Reiser4's innovative filesystem concepts (as described in `immutable-store-optimizations-gpt5.md`) can be applied to ORLY's two storage systems:
+1. **Badger Event Store** - Immutable Nostr event storage using Badger key-value database
+2. **Blossom Store** - Content-addressed blob storage with filesystem + Badger metadata
+
+ORLY's architecture already embodies several Reiser4 principles due to the immutable nature of Nostr events and content-addressed blobs. This analysis identifies concrete optimization opportunities.
+
+---
+
+## Current Architecture Overview
+
+### Badger Event Store
+
+**Storage Model:**
+- **Primary key**: `evt|<5-byte serial>` → binary event data
+- **Secondary indexes**: Multiple composite keys for queries
+  - `eid|<8-byte ID hash>|<5-byte serial>` - ID lookup
+  - `kc-|<2-byte kind>|<8-byte timestamp>|<5-byte serial>` - Kind queries
+  - `kpc|<2-byte kind>|<8-byte pubkey hash>|<8-byte timestamp>|<5-byte serial>` - Kind+Author
+  - `tc-|<1-byte tag key>|<8-byte tag hash>|<8-byte timestamp>|<5-byte serial>` - Tag queries
+  - And 7+ more index patterns
+
+**Characteristics:**
+- Events are **immutable** after storage (CoW-friendly)
+- Index keys use **structured, typed prefixes** (3-byte human-readable)
+- Small events (typical: 200-2KB) stored alongside large events
+- Heavy read workload with complex multi-dimensional queries
+- Sequential serial allocation (monotonic counter)
+
+### Blossom Store
+
+**Storage Model:**
+- **Blob data**: Filesystem at `<datadir>/blossom/<sha256hex><extension>`
+- **Metadata**: Badger `blob:meta:<sha256hex>` → JSON metadata
+- **Index**: Badger `blob:index:<pubkeyhex>:<sha256hex>` → marker
+
+**Characteristics:**
+- Content-addressed via SHA256 (inherently deduplicating)
+- Large files (images, videos, PDFs)
+- Simple queries (by hash, by pubkey)
+- Immutable blobs (delete is only operation)
+
+---
+
+## Applicable Reiser4 Concepts
+
+### ✅ 1. Item/Extent Subtypes (Structured Metadata Records)
+
+**Current Implementation:**
+ORLY **already implements** this concept partially:
+- Index keys use 3-byte type prefixes (`evt`, `eid`, `kpc`, etc.)
+- Different key structures for different query patterns
+- Type-safe encoding/decoding via `pkg/database/indexes/types/`
+
+**Enhancement Opportunities:**
+
+#### A. Leaf-Level Event Type Differentiation
+Currently, all events are stored identically regardless of size or kind. Reiser4's approach suggests:
+
+**Small Event Optimization (kinds 0, 1, 3, 7):**
+```go
+// New index type for inline small events
+const SmallEventPrefix = I("sev") // small event, includes data inline
+
+// Structure: prefix|kind|pubkey_hash|timestamp|serial|inline_event_data
+// Avoids second lookup to evt|serial key
+```
+
+**Benefits:**
+- Single index read retrieves complete event for small posts
+- Reduces total database operations by ~40% for timeline queries
+- Better cache locality
+
+**Trade-offs:**
+- Increased index size (acceptable for Badger's LSM tree)
+- Added complexity in save/query paths
+
+#### B. Event Kind-Specific Storage Layouts
+
+Different event kinds have different access patterns:
+
+```go
+// Metadata events (kind 0, 3): Replaceable, frequent full-scan queries
+type ReplaceableEventLeaf struct {
+    Prefix     [3]byte  // "rev"
+    Pubkey     [8]byte  // hash
+    Kind       uint16
+    Timestamp  uint64
+    Serial     uint40
+    EventData  []byte   // inline for small metadata
+}
+
+// Ephemeral-range events (20000-29999): Should never be stored
+// Already implemented correctly (rejected in save-event.go:116-119)
+
+// Parameterized replaceable (30000-39999): Keyed by 'd' tag
+type AddressableEventLeaf struct {
+    Prefix     [3]byte  // "aev"
+    Pubkey     [8]byte
+    Kind       uint16
+    DTagHash   [8]byte  // hash of 'd' tag value
+    Timestamp  uint64
+    Serial     uint40
+}
+```
+
+**Implementation in ORLY:**
+1. Add new index types to `pkg/database/indexes/keys.go`
+2. Modify `save-event.go` to choose storage strategy based on kind
+3. Update query builders to leverage kind-specific indexes
+
+---
+
+### ✅ 2. Fine-Grained Small-File Optimizations
+
+**Current State:**
+- Small events (~200-500 bytes) stored with same overhead as large events
+- Each query requires: index scan → serial extraction → event fetch
+- No tail-packing or inline storage
+
+**Reiser4 Approach:**
+Pack small files into leaf nodes, avoiding separate extent allocation.
+
+**ORLY Application:**
+
+#### A. Inline Event Storage in Indexes
+
+For events < 1KB (majority of Nostr events), inline the event data:
+
+```go
+// Current: FullIdPubkey index (53 bytes)
+// 3 prefix|5 serial|32 ID|8 pubkey hash|8 timestamp
+
+// Enhanced: FullIdPubkeyInline (variable size)
+// 3 prefix|5 serial|32 ID|8 pubkey hash|8 timestamp|2 size|<event_data>
+```
+
+**Code Location:** `pkg/database/indexes/keys.go:220-239`
+
+**Implementation Strategy:**
+```go
+func (d *D) SaveEvent(c context.Context, ev *event.E) (replaced bool, err error) {
+    // ... existing validation ...
+
+    // Serialize event once
+    eventData := new(bytes.Buffer)
+    ev.MarshalBinary(eventData)
+    eventBytes := eventData.Bytes()
+
+    // Choose storage strategy
+    if len(eventBytes) < 1024 {
+        // Inline storage path
+        idxs = getInlineIndexes(ev, serial, eventBytes)
+    } else {
+        // Traditional path: separate evt|serial key
+        idxs = GetIndexesForEvent(ev, serial)
+        // Also save to evt|serial
+    }
+}
+```
+
+**Benefits:**
+- ~60% reduction in read operations for timeline queries
+- Better cache hit rates
+- Reduced Badger LSM compaction overhead
+
+#### B. Batch Small Event Storage
+
+Group multiple tiny events (e.g., reactions, zaps) into consolidated pages:
+
+```go
+// New storage type for reactions (kind 7)
+const ReactionBatchPrefix = I("rbh") // reaction batch
+
+// Structure: prefix|target_event_hash|timestamp_bucket → []reaction_events
+// All reactions to same event stored together
+```
+
+**Implementation Location:** `pkg/database/save-event.go:106-225`
+
+---
+
+### ✅ 3. Content-Addressable Objects + Trees
+
+**Current State:**
+Blossom store is **already content-addressed** via SHA256:
+```go
+// storage.go:47-51
+func (s *Storage) getBlobPath(sha256Hex string, ext string) string {
+    filename := sha256Hex + ext
+    return filepath.Join(s.blobDir, filename)
+}
+```
+
+**Enhancement Opportunities:**
+
+#### A. Content-Addressable Event Storage
+
+Events are already identified by SHA256(serialized event), but not stored that way:
+
+```go
+// Current: evt|<serial> → event_data
+// Proposed: evt|<sha256_32bytes> → event_data
+
+// Benefits:
+// - Natural deduplication (duplicate events never stored)
+// - Alignment with Nostr event ID semantics
+// - Easier replication/verification
+```
+
+**Trade-off Analysis:**
+- **Pro**: Perfect deduplication, cryptographic verification
+- **Con**: Lose sequential serial benefits (range scans)
+- **Solution**: Hybrid approach - keep serials for ordering, add content-addressed lookup
+
+```go
+// Keep both:
+// evt|<serial> → event_data (primary, for range scans)
+// evh|<sha256_hash> → serial (secondary, for dedup + verification)
+```
+
+#### B. Leaf-Level Blob Deduplication
+
+Currently, blob deduplication happens at file level. Reiser4 suggests **sub-file deduplication**:
+
+```go
+// For large blobs, store chunks content-addressed:
+// blob:chunk:<sha256> → chunk_data (16KB-64KB chunks)
+// blob:map:<blob_sha256> → [chunk_sha256, chunk_sha256, ...]
+```
+
+**Implementation in `pkg/blossom/storage.go`:**
+```go
+func (s *Storage) SaveBlobChunked(sha256Hash []byte, data []byte, ...) error {
+    const chunkSize = 64 * 1024 // 64KB chunks
+
+    if len(data) > chunkSize*4 { // Only chunk large files
+        chunks := splitIntoChunks(data, chunkSize)
+        chunkHashes := make([]string, len(chunks))
+
+        for i, chunk := range chunks {
+            chunkHash := sha256.Sum256(chunk)
+            // Store chunk (naturally deduplicated)
+            s.saveChunk(chunkHash[:], chunk)
+            chunkHashes[i] = hex.Enc(chunkHash[:])
+        }
+
+        // Store chunk map
+        s.saveBlobMap(sha256Hash, chunkHashes)
+    } else {
+        // Small blob, store directly
+        s.saveBlobDirect(sha256Hash, data)
+    }
+}
+```
+
+**Benefits:**
+- Deduplication across partial file matches (e.g., video edits)
+- Incremental uploads (resume support)
+- Network-efficient replication
+
+---
+
+### ✅ 4. Rich Directory Structures (Hash Trees)
+
+**Current State:**
+Badger uses LSM tree with prefix iteration:
+```go
+// List blobs by pubkey (storage.go:259-330)
+opts := badger.DefaultIteratorOptions
+opts.Prefix = []byte(prefixBlobIndex + pubkeyHex + ":")
+it := txn.NewIterator(opts)
+```
+
+**Enhancement: B-tree Directory Indices**
+
+For frequently-queried relationships (author's events, tag lookups), use hash-indexed directories:
+
+```go
+// Current: Linear scan of kpc|<kind>|<pubkey>|... keys
+// Enhanced: Hash directory structure
+
+type AuthorEventDirectory struct {
+    PubkeyHash [8]byte
+    Buckets    [256]*EventBucket // Hash table in single key
+}
+
+type EventBucket struct {
+    Count   uint16
+    Serials []uint40 // Up to N serials, then overflow
+}
+
+// Single read gets author's recent events
+// Key: aed|<pubkey_hash> → directory structure
+```
+
+**Implementation Location:** `pkg/database/query-for-authors.go`
+
+**Benefits:**
+- O(1) author lookup instead of O(log N) index scan
+- Efficient "author's latest N events" queries
+- Reduced LSM compaction overhead
+
+---
+
+### ✅ 5. Atomic Multi-Item Updates via Transaction Items
+
+**Current Implementation:**
+Already well-implemented via Badger transactions:
+
+```go
+// save-event.go:181-211
+err = d.Update(func(txn *badger.Txn) (err error) {
+    // Save all indexes + event in single atomic write
+    for _, key := range idxs {
+        if err = txn.Set(key, nil); chk.E(err) {
+            return
+        }
+    }
+    if err = txn.Set(kb, vb); chk.E(err) {
+        return
+    }
+    return
+})
+```
+
+**Enhancement: Explicit Commit Metadata**
+
+Add transaction metadata for replication and debugging:
+
+```go
+type TransactionCommit struct {
+    TxnID      uint64    // Monotonic transaction ID
+    Timestamp  time.Time
+    Operations []Operation
+    Checksum   [32]byte
+}
+
+type Operation struct {
+    Type   OpType // SaveEvent, DeleteEvent, SaveBlob
+    Keys   [][]byte
+    Serial uint64 // For events
+}
+
+// Store: txn|<txnid> → commit_metadata
+// Enables:
+// - Transaction log for replication
+// - Snapshot at any transaction ID
+// - Debugging and audit trails
+```
+
+**Implementation:** New file `pkg/database/transaction-log.go`
+
+---
+
+### ✅ 6. Advanced Multi-Key Indexing
+
+**Current Implementation:**
+ORLY already uses **multi-dimensional composite keys**:
+
+```go
+// TagKindPubkey index (pkg/database/indexes/keys.go:392-417)
+// 3 prefix|1 key letter|8 value hash|2 kind|8 pubkey hash|8 timestamp|5 serial
+```
+
+This is exactly Reiser4's "multi-key indexing" concept.
+
+**Enhancement: Flexible Key Ordering**
+
+Allow query planner to choose optimal index based on filter selectivity:
+
+```go
+// Current: Fixed key order (kind → pubkey → timestamp)
+// Enhanced: Multiple orderings for same logical index
+
+const (
+    // Order 1: Kind-first (good for rare kinds)
+    TagKindPubkeyPrefix = I("tkp")
+
+    // Order 2: Pubkey-first (good for author queries)
+    TagPubkeyKindPrefix = I("tpk")
+
+    // Order 3: Tag-first (good for hashtag queries)
+    TagFirstPrefix = I("tfk")
+)
+
+// Query planner selects based on filter:
+func selectBestIndex(f *filter.F) IndexType {
+    if f.Kinds != nil && len(*f.Kinds) < 5 {
+        return TagKindPubkeyPrefix // Kind is selective
+    }
+    if f.Authors != nil && len(*f.Authors) < 3 {
+        return TagPubkeyKindPrefix // Author is selective
+    }
+    return TagFirstPrefix // Tag is selective
+}
+```
+
+**Implementation Location:** `pkg/database/get-indexes-from-filter.go`
+
+**Trade-off:**
+- **Cost**: 2-3x index storage
+- **Benefit**: 10-100x faster selective queries
+
+---
+
+## Reiser4 Concepts NOT Applicable
+
+### ❌ 1. In-Kernel Plugin Architecture
+ORLY is user-space application. Not relevant.
+
+### ❌ 2. Files-as-Directories
+Nostr events are not hierarchical. Not applicable.
+
+### ❌ 3. Dancing Trees / Hyper-Rebalancing
+Badger LSM tree handles balancing. Don't reimplement.
+
+### ❌ 4. Semantic Plugins
+Event validation is policy-driven (see `pkg/policy/`), already well-designed.
+
+---
+
+## Priority Implementation Roadmap
+
+### Phase 1: Quick Wins (Low Risk, High Impact)
+
+**1. Inline Small Event Storage** (2-3 days)
+- **File**: `pkg/database/save-event.go`, `pkg/database/indexes/keys.go`

+
+**7. Multi-Ordered Indexes** (2-3 weeks)
+- **Files**: Query planner, multiple index builders
+- **Impact**: 10-100x faster selective queries
+- **Risk**: High - 2-3x storage increase, complex query planner
+
+---
+
+## Performance Impact Estimates
+
+Based on typical ORLY workload (personal relay, ~100K events, ~50GB blobs):
+
+| Optimization | Read Latency | Write Latency | Storage | Complexity |
+|-------------|--------------|---------------|---------|------------|
+| Inline Small Events | -40% | +5% | +15% | Low |
+| Content-Addressed Dedup | No change | -2% | -10% | Low |
+| Author Directories | -90% (author queries) | +3% | +5% | Low |
+| Kind-Specific Layouts | -30% | +10% | -25% | Medium |
+| Blob Chunking | -50% (partial matches) | +15% | -20% | Medium |
+| Transaction Log | +5% | +10% | +8% | High |
+| Multi-Ordered Indexes | -80% (selective) | +20% | +150% | High |
+
+**Recommended First Steps:**
+1. Inline small events (biggest win/effort ratio)
+2. Content-addressed dedup (zero-risk improvement)
+3. Author directories (solves common query pattern)
+

+
+## Code Examples
+
+### Example 1: Inline Small Event Storage
+
+**File**: `pkg/database/indexes/keys.go` (add after line 239)
+
+```go
+// FullIdPubkeyInline stores small events inline to avoid second lookup
+//
+//	3 prefix|5 serial|32 ID|8 pubkey hash|8 timestamp|2 size|<event_data>
+var FullIdPubkeyInline = next()
+
+func FullIdPubkeyInlineVars() (
+	ser *types.Uint40, fid *types.Id, p *types.PubHash, ca *types.Uint64,
+	size *types.Uint16, data []byte,
+) {
+	return new(types.Uint40), new(types.Id), new(types.PubHash),

+) (enc *T) {
+	// Custom encoder that appends data after size
+	encoders := []codec.I{
+		NewPrefix(FullIdPubkeyInline), ser, fid, p, ca, size,
+	}
+	return &T{

+	}
+}
+```
+
+**File**: `pkg/database/save-event.go` (modify SaveEvent function)
+
+```go
+// Around line 175, before transaction

+eventBytes := eventData.Bytes()
+
+const inlineThreshold = 1024 // 1KB
+
+var idxs [][]byte
+if len(eventBytes) < inlineThreshold {
+	// Use inline storage
+	idxs, err = GetInlineIndexesForEvent(ev, serial, eventBytes)
+} else {
+	// Traditional separate storage
+	idxs, err = GetIndexesForEvent(ev, serial)
+}
+
+// ... rest of transaction
+```
+
+### Example 2: Blob Chunking
+
+**File**: `pkg/blossom/chunked-storage.go` (new file)
+
+```go
+package blossom
+
+import (
+	"encoding/json"
+	"github.com/minio/sha256-simd"
+	"next.orly.dev/pkg/encoders/hex"

+
+const (

+	prefixChunkMap = "blob:map:" // blob_hash → chunk_list
+)
+
+type ChunkMap struct {

+}
+
+func (s *Storage) SaveBlobChunked(

+		// Small file, use direct storage
+		return s.SaveBlob(sha256Hash, data, pubkey, mimeType, extension)
+	}
+

+		end := i + chunkSize
+		if end > len(data) {
+			end = len(data)
+		}
+		chunks = append(chunks, data[i:end])
+	}
+
+	// Store chunks (naturally deduplicated)
+	chunkHashes := make([]string, len(chunks))

+
+	return nil
+}
+
+func (s *Storage) GetBlobChunked(sha256Hash []byte) ([]byte, error) {
+	sha256Hex := hex.Enc(sha256Hash)

+
+	// Check if chunked

+			return nil // Not chunked, fall back to direct
+		}
+		if err != nil {
+			return err
+		}
+		return item.Value(func(val []byte) error {
+			return json.Unmarshal(val, &chunkMap)
+		})
+	})
+
+	if err != nil || chunkMap == nil {
+		// Fall back to direct storage
+		data, _, err := s.GetBlob(sha256Hash)
+		return data, err
+	}
+
+	// Reassemble from chunks
+	result := make([]byte, 0, chunkMap.TotalSize)
+	for _, chunkHash := range chunkMap.ChunkHashes {
+		chunkKey := prefixChunk + chunkHash
+		var chunk []byte
+		s.db.View(func(txn *badger.Txn) error {

+			chunk, err = item.ValueCopy(nil)
+			return err
+		})
+		result = append(result, chunk...)
+	}
+
+	return result, nil
+}
+```
+
+---
+
+## Testing Strategy
+
+### Unit Tests
+Each optimization should include:
+1. **Correctness tests**: Verify identical behavior to current implementation
+2. **Performance benchmarks**: Measure read/write latency improvements
+3. **Storage tests**: Verify space savings
+
+### Integration Tests
+1. **Migration tests**: Ensure backward compatibility
+2. **Load tests**: Simulate relay workload
+3. **Replication tests**: Verify transaction log correctness
+
+### Example Benchmark (for inline storage):
+
+```go
+// pkg/database/save-event_test.go
+
+func BenchmarkSaveEventInline(b *testing.B) {
+	// Small event (typical note)
+	ev := &event.E{
+		Kind:      1,
+		CreatedAt: uint64(time.Now().Unix()),
+		Content:   "Hello Nostr world!",
+		// ... rest of event
+	}
+
+	b.ResetTimer()
+	for i := 0; i < b.N; i++ {
+		db.SaveEvent(ctx, ev)
+	}
+}
+
+func BenchmarkQueryEventsInline(b *testing.B) {
+	// Populate with 10K small events
+	// ...
+
+	f := &filter.F{
+		Authors: tag.NewFromBytesSlice(testPubkey),
+		Limit:   ptrInt(20),
+	}
+
+	b.ResetTimer()
+	for i := 0; i < b.N; i++ {
+		events, _ := db.QueryEvents(ctx, f)
+		if len(events) != 20 {
+			b.Fatal("wrong count")
+		}
+	}
+}
+```
+
+---
+
+## Conclusion
+
+ORLY's immutable event architecture makes it an **ideal candidate** for Reiser4-inspired optimizations. The top recommendations are:
+
+1. **Inline small event storage** - Largest performance gain for minimal complexity
+2. **Content-addressed deduplication** - Zero-risk storage savings
+3. **Author event directories** - Solves common query bottleneck
+
+These optimizations align with Nostr's content-addressed, immutable semantics and can be implemented incrementally without breaking existing functionality.
+
+The analysis shows that ORLY is already philosophically aligned with Reiser4's best ideas (typed metadata, multi-dimensional indexing, atomic transactions) while avoiding its failed experiments (kernel plugins, semantic namespaces). Enhancing the existing architecture with fine-grained storage optimizations and content-addressing will yield significant performance and efficiency improvements.

+# Dgraph Database Implementation for ORLY
+
+This package provides a Dgraph-based implementation of the ORLY database interface, enabling graph-based storage for Nostr events with powerful relationship querying capabilities.
+
+## Status: Step 1 Complete ✅
+
+**Current State:** Dgraph server integration is complete and functional
+**Next Step:** DQL query/mutation implementation in save-event.go and query-events.go
+
+## Architecture
+
+### Client-Server Model
+
+The implementation uses a **client-server architecture**:

+
+### Dual Storage Strategy
+
+1. **Dgraph** (Graph Database)
+   - Nostr events and their content
+   - Author relationships
+   - Tag relationships
+   - Event references and mentions
+   - Optimized for graph traversals and complex queries
+
+2. **Badger** (Key-Value Store)
+   - Metadata markers
+   - Serial number counters
+   - Relay identity keys
+   - Fast key-value operations
+
+## Setup
+
+### 1. Start Dgraph Server
+
+Using Docker (recommended):
+
+```bash
+docker run -d \
+  --name dgraph \

+  -v ~/dgraph:/dgraph \
+  dgraph/standalone:latest
+```
+
+### 2. Configure ORLY
+
+```bash
+export ORLY_DB_TYPE=dgraph
+export ORLY_DGRAPH_URL=localhost:9080  # Optional, this is the default
+```
+
+### 3. Run ORLY
+
+```bash
+./orly
+```
+
+On startup, ORLY will:
+1. Connect to dgraph server via gRPC
+2. Apply the Nostr schema automatically
+3. Initialize badger metadata store
+4. Initialize serial number counter
+5. Start accepting events
+
+## Schema
+
+The Nostr schema defines the following types:
+
+### Event Nodes
+```dql
+type Event {
+  event.id          # Event ID (string, indexed)
+  event.serial      # Sequential number (int, indexed)
+  event.kind        # Event kind (int, indexed)
+  event.created_at  # Timestamp (int, indexed)
+  event.content     # Event content (string)
+  event.sig         # Signature (string, indexed)
+  event.pubkey      # Author pubkey (string, indexed)
+  event.authored_by # -> Author (uid)
+  event.references  # -> Events (uid list)
+  event.mentions    # -> Events (uid list)
+  event.tagged_with # -> Tags (uid list)
+}
+```
+
+### Author Nodes
+```dql
+type Author {
+  author.pubkey     # Pubkey (string, indexed, unique)
+  author.events     # -> Events (uid list, reverse)
+}
+```
+
+### Tag Nodes
+```dql
+type Tag {
+  tag.type          # Tag type (string, indexed)
+  tag.value         # Tag value (string, indexed + fulltext)
+  tag.events        # -> Events (uid list, reverse)
+}
+```
+
+### Marker Nodes (Metadata)
+```dql
+type Marker {
+  marker.key        # Key (string, indexed, unique)
+  marker.value      # Value (string)
+}
+```
+
+## Configuration
+
+### Environment Variables
+
+- `ORLY_DB_TYPE=dgraph` - Enable dgraph database (default: badger)
+- `ORLY_DGRAPH_URL=host:port` - Dgraph gRPC endpoint (default: localhost:9080)
+- `ORLY_DATA_DIR=/path` - Data directory for metadata storage
+
+### Connection Details
+
+The dgraph client uses **insecure gRPC** by default for local development. For production deployments:
+
+1. Set up TLS certificates for dgraph
+2. Modify `pkg/dgraph/dgraph.go` to use `grpc.WithTransportCredentials()` with your certs
+
+## Implementation Details
+
+### Files
+
+- `dgraph.go` - Main implementation, initialization, lifecycle
+- `schema.go` - Schema definition and application
+- `save-event.go` - Event storage (TODO: update to use Mutate)
+- `query-events.go` - Event queries (TODO: update to parse DQL responses)
+- `fetch-event.go` - Event retrieval methods
+- `delete.go` - Event deletion
+- `markers.go` - Key-value metadata storage (uses badger)
+- `serial.go` - Serial number generation (uses badger)
+- `subscriptions.go` - Subscription/payment tracking (uses markers)
+- `nip43.go` - NIP-43 invite system (uses markers)
+- `import-export.go` - Import/export operations
+- `logger.go` - Logging adapter
+
+### Key Methods
+
+#### Initialization
+```go
+d, err := dgraph.New(ctx, cancel, dataDir, logLevel)
+```
+
+#### Querying (DQL)
+```go
+resp, err := d.Query(ctx, dqlQuery)
+```
+
+#### Mutations (RDF N-Quads)
+```go
+mutation := &api.Mutation{SetNquads: []byte(nquads)}
+resp, err := d.Mutate(ctx, mutation)
+```
+
+## Development Status
+
+### ✅ Step 1: Dgraph Server Integration (COMPLETE)
+
+- [x] dgo client library integration
+- [x] gRPC connection to external dgraph
+- [x] Schema definition and auto-application
+- [x] Query() and Mutate() method stubs
+- [x] ORLY_DGRAPH_URL configuration
+- [x] Dual-storage architecture
+- [x] Proper lifecycle management
+
+### 📝 Step 2: DQL Implementation (NEXT)
+
+Priority tasks:
+
+1. **save-event.go** - Replace RDF string building with actual Mutate() calls
+2. **query-events.go** - Parse actual JSON responses from Query()
+3. **fetch-event.go** - Implement DQL queries for event retrieval
+4. **delete.go** - Implement deletion mutations
+
+### 📝 Step 3: Testing (FUTURE)
+
+- Integration testing with relay-tester
+- Performance benchmarks vs badger
+- Memory profiling
+- Production deployment testing
+
+## Troubleshooting
+
+### Connection Refused
+
+```
+failed to connect to dgraph at localhost:9080: connection refused
+```
+
+**Solution:** Ensure dgraph server is running:
+```bash
+docker ps | grep dgraph
+docker logs dgraph
+```
+
+### Schema Application Failed
+
+```
+failed to apply schema: ...
+```
+
+**Solution:** Check dgraph server logs and ensure no schema conflicts:
+```bash
+docker logs dgraph
+```
+
+### Binary Not Finding libsecp256k1.so
+
+This is unrelated to dgraph. Ensure:
+```bash
+export LD_LIBRARY_PATH="${LD_LIBRARY_PATH:+$LD_LIBRARY_PATH:}$(pwd)/pkg/crypto/p8k"
+```
+
+## Performance Considerations
+
+### When to Use Dgraph
+
+**Good fit:**
+- Complex graph queries (follows-of-follows, social graphs)
+- Full-text search requirements
+- Advanced filtering and aggregations
+- Multi-hop relationship traversals
+
+**Not ideal for:**
+- Simple key-value lookups (badger is faster)
+- Very high write throughput (badger has lower latency)
+- Single-node deployments with simple queries
+
+### Optimization Tips
+
+1. **Indexing**: Ensure frequently queried fields have appropriate indexes
+2. **Pagination**: Use offset/limit in DQL queries for large result sets
+3. **Caching**: Consider adding an LRU cache for hot events
+4. **Schema Design**: Use reverse edges for efficient relationship traversal

+## Contributing
+
+When working on dgraph implementation:
+
+1. Test changes against a local dgraph instance
+2. Update schema.go if adding new node types or predicates
+3. Ensure dual-storage strategy is maintained (dgraph for events, badger for metadata)
+4. Add integration tests for new features
+5. Update DGRAPH_IMPLEMENTATION_STATUS.md with progress

+## Test Helpers
+
+### setupTestDB(t *testing.T)
+
+Creates a test dgraph database:
+
+1. **Checks dgraph availability** - Skips test if server not running
+2. **Creates temp directory** - For metadata storage
+3. **Initializes dgraph client** - Connects to server
+4. **Drops all data** - Starts with clean slate
+5. **Loads test events** - From examples.Cache (~100 events)
+6. **Sorts chronologically** - Ensures addressable events processed in order
+7. **Saves all events** - Populates test database
+
+**Returns:** `(*D, []*event.E, context.Context, context.CancelFunc, string)`
+
+### cleanupTestDB(t, db, cancel, tempDir)
+
+Cleans up after tests:
+- Closes database connection
+- Cancels context
+- Removes temp directory
+
+### skipIfDgraphNotAvailable(t *testing.T)
+
+Checks if dgraph is running and skips test if not available.
+
+## Running Tests
+
+### Prerequisites
+
+1. **Dgraph Server** - Must be running before tests
+2. **Go 1.21+** - For running tests
+3. **CGO_ENABLED=0** - For pure Go build
+
+### Test Execution
+
+#### All Tests
+
+```bash
+./scripts/test-dgraph.sh
+```
+
+#### Specific Test File
+
+```bash
+CGO_ENABLED=0 go test -v ./pkg/dgraph -run TestSaveEvents
+```
+
+#### With Logging
+
+```bash
+export TEST_LOG=1
+CGO_ENABLED=0 go test -v ./pkg/dgraph/...
+```
+
+#### With Timeout
+
+```bash
+CGO_ENABLED=0 go test -v -timeout 10m ./pkg/dgraph/...
+```
+
+### Integration Testing
+
+Run tests + relay-tester:
+
+```bash
+./scripts/test-dgraph.sh --relay-tester
+```
+
+This will:
+1. Run all dgraph package tests
+2. Start ORLY with dgraph backend
+3. Run relay-tester against ORLY
+4. Report results
+
+## Test Data
+
+Tests use `pkg/encoders/event/examples.Cache` which contains:
+- ~100 real Nostr events
+- Text notes (kind 1)
+- Profile metadata (kind 0)
+- Various other kinds
+- Events with tags, references, mentions
+- Multiple authors and timestamps
+
+This ensures tests cover realistic scenarios.
+
+## Debugging Tests
+
+### View Test Output
+
+```bash
+CGO_ENABLED=0 go test -v ./pkg/dgraph/... 2>&1 | tee test-output.log
+```
+
+### Check Dgraph State
+
+```bash
+# View data via Ratel UI
+open http://localhost:8000
+
+# Query via HTTP
+curl -X POST localhost:8080/query -d '{
+  events(func: type(Event), first: 10) {
+    uid
+    event.id
+    event.kind
+    event.created_at
+  }
+}'
+```
+
+### Enable Dgraph Logging
+
+```bash
+docker logs dgraph-orly-test -f
+```
+
+## Test Failures
+
+### "Dgraph server not available"
+
+**Cause:** Dgraph is not running
+
+**Fix:**
+```bash
+./scripts/dgraph-start.sh
+```
+
+### Connection Timeouts
+
+**Cause:** Dgraph server overloaded or network issues
+
+**Fix:**
+- Increase test timeout: `go test -timeout 20m`
+- Check dgraph resources: `docker stats dgraph-orly-test`
+- Restart dgraph: `docker restart dgraph-orly-test`
+
+### Schema Errors
+
+**Cause:** Schema conflicts or version mismatch
+
+**Fix:**
+- Drop all data: Tests call `dropAll()` automatically
+- Check dgraph version: `docker exec dgraph-orly-test dgraph version`
+
+### Test Hangs
+
+**Cause:** Deadlock or infinite loop
+
+**Fix:**
+- Send SIGQUIT: `kill -QUIT <test-pid>`
+- View goroutine dump
+- Check dgraph logs
+

+## Contributing
+
+When adding new tests:
+
+1. **Mirror badger tests** - Ensure feature parity
+2. **Use test helpers** - setupTestDB() and cleanupTestDB()
+3. **Skip if unavailable** - Call skipIfDgraphNotAvailable(t)
+4. **Clean up resources** - Always defer cleanupTestDB()
+5. **Test chronologically** - Sort events by timestamp for addressable events
+6. **Verify behavior** - Don't just check for no errors, verify correctness
