- 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'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:
|
|
1. **3a**: Query Operations (2 weeks)
|
|
2. **3b**: Item Retrieval (2 weeks)
|
|
3. **3c**: Write Operations (1 week)
|
|
4. **3d**: Delete Operations (1 week)
|
|
5. **3e**: Aggregations (1 week)
|
|
|
|
**Total**: 8 weeks with proper testing

## 🎓 Key Learnings
|
|
|
|
### What Worked Exceptionally Well ✅
|
|
|
|
1. **Incremental Approach**
|
|
- One repository at a time prevented overwhelm
|
|
- Each conversion refined the pattern
|
|
- Build stayed stable throughout
|
|
|
|
2. **Backward Compatibility**
|
|
- Keeping sync methods prevented breaking changes
|
|
- Gradual migration possible
|
|
- Zero user impact
|
|
|
|
3. **Documentation First**
|
|
- Having comprehensive docs saved time
|
|
- Clear tracking of progress
|
|
- Stakeholder communication easy
|
|
|
|
4. **Pattern Consistency**
|
|
- Same approach for all repositories
|
|
- Predictable file structure
|
|
- Easy to review
|
|
|
|
### Challenges Overcome ⚠️
|
|
|
|
1. **Finding Consumers**
|
|
- Solution: Systematic use of `Select-String` and `find_symbol`
|
|
|
|
2. **Sync-by-Design Interfaces**
|
|
- Solution: `.GetAwaiter().GetResult()` with documentation
|
|
|
|
3. **Complex Transaction Logic**
|
|
- Solution: Careful step-by-step async conversion
|
|
- Example: PeopleRepository UpdatePeople method
|
|
|
|
4. **Build Time**
|
|
- Solution: Layer-by-layer verification
|
