🔄⚡ Hybrid Storage Performance & Real-time Sync

This release brings two major enhancements to hybrid storage: bi-directional sync with live progress updates and 3-5x faster initial sync performance.

🎯 Key Features

Bi-directional Sync with Real-time SSE Progress (PR #229)

  • Complete Synchronization: "Sync now" button now performs PULL from Cloudflare + PUSH to Cloudflare
  • Problem Solved: MCP-created memories (direct Cloudflare writes) previously required server restart to appear locally
  • Live Progress Updates: Real-time SSE events broadcast sync progress every 10 memories
  • Enhanced UX:
    • Progress updates: "Syncing: 50/100 (50%)"
    • Completion notifications: "Pulled 50 from Cloudflare, pushed 25 to Cloudflare"
    • Dashboard auto-refreshes when sync completes

3-5x Faster Initial Sync Performance (PR #230)

  • Performance Metrics:
    • Before: ~5.5 memories/second (8 minutes for 2,619 memories)
    • After: ~15-30 memories/second (1.5-3 minutes for 2,619 memories)
  • Optimizations:
    • Bulk hash loading eliminates 2,619 individual DB queries
    • Parallel processing with 15 concurrent operations
    • Batch sizes increased from 100 to 500 memories (5x fewer API calls)
  • Benchmark Results: 78% reduction in Cloudflare API calls (27 → 6 for 2,619 memories)

📊 Combined Impact

Users with large memory databases (1000+ memories) will experience:

  • Instant sync visibility: See MCP-created memories immediately after manual sync
  • Dramatically faster initial sync: 3-5x performance improvement
  • Real-time progress tracking: Know exactly what's happening during sync
  • Better UX: Dashboard auto-refreshes with latest data

🔧 Technical Details

Files Modified:

  • src/mcp_memory_service/storage/hybrid.py - Bi-directional sync, parallel processing
  • src/mcp_memory_service/storage/sqlite_vec.py - Bulk hash loading method
  • src/mcp_memory_service/web/api/sync.py - Enhanced sync endpoint
  • src/mcp_memory_service/web/sse.py - Progress event broadcasting
  • src/mcp_memory_service/web/static/app.js - SSE event listeners

New Configuration:

  • MCP_HYBRID_SYNC_OWNER - Control which process handles Cloudflare sync (http/mcp/both)

🛡️ Backward Compatibility

  • Zero breaking changes - All existing sync operations enhanced transparently
  • Default behavior preserved - "both" sync owner for compatibility
  • Graceful fallback - Works with or without Cloudflare connectivity

📚 Documentation

  • Full details: CHANGELOG.md
  • Performance benchmarks: scripts/benchmarks/benchmark_hybrid_sync.py
  • Setup guide: Wiki
