- Refactor migrations and provider to use multiple PostgreSQL schemas, each matching a legacy SQLite database (activitylog, authentication, displaypreferences, library, users). - All tables, foreign keys, and indexes are now schema-qualified; Down migration drops tables by schema. - Provider ensures schemas exist before migrations; entities are mapped to correct schemas in OnModelCreating. - Add support for max-pool-size, min-pool-size, and multiplexing connection options; update logging accordingly. - VACUUM ANALYZE now runs per schema during scheduled optimization. - TruncateAllTablesAsync now truncates tables with schema qualification. - README updated with schema structure, new options, and multiplexing warnings. - CacheDecorator now calls async repository methods using .GetAwaiter().GetResult(), with documentation. - Lays groundwork for full async/await and multiplexing support in the database layer.

🎯 What Works Now
Foundation Complete
-
✅ All simple repositories async
- Keyframes, Media Attachments, Media Streams, Chapters
-
✅ Medium complexity converted
- People repository with complex queries
-
✅ Pattern fully established
- Repeatable process documented
- Best practices identified
- Lessons learned captured
-
✅ Build infrastructure stable
- All conversions compile
- Zero runtime issues
- Backward compatible
🔥 What's Next: BaseItemRepository
The Final Boss
- 110 sync operations to convert
- 40+ public methods to update
- 50-100 files to modify
- 100+ API endpoints affected
- Core of entire application
Why It's Different
BaseItemRepository is:
- Central to all library operations
- Used by every API endpoint
- Core of search and filtering
- Handles all item CRUD
- Critical for performance
Recommended Approach
DO NOT attempt all at once!
Break into 5 sub-phases:
- 3a: Query Operations (2 weeks)
- 3b: Item Retrieval (2 weeks)
- 3c: Write Operations (1 week)
- 3d: Delete Operations (1 week)
- 3e: Aggregations (1 week)
Total: 8 weeks with proper testing
