- BBolt B+tree backend with sequential access patterns for spinning disks - Write batching (5000 events / 128MB / 30s flush) to reduce disk thrashing - Adjacency list storage for graph data (one key per vertex, not per edge) - Bloom filter for fast negative edge existence checks (~12MB for 10M edges) - No query cache (saves RAM, B+tree reads are fast enough on HDD) - Migration tool: orly migrate --from badger --to bbolt - Configuration: ORLY_BBOLT_* environment variables Files modified: - app/config/config.go: Added BBolt configuration options - main.go: Added migrate subcommand and BBolt config wiring - pkg/database/factory.go: Added BBolt factory registration - pkg/bbolt/*: New BBolt database backend implementation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
