wjones d623cd03a9 Enable EF Core SplitQuery for PostgreSQL provider
Configured QuerySplittingBehavior.SplitQuery in PostgresDatabaseProvider to optimize performance for queries with multiple Include() statements. This prevents cartesian explosion, eliminates EF Core warnings, and aligns with best practices for handling related collections in PostgreSQL.

Current State

Build Status

  • Compiles: No errors
  • Warnings: Resolved
  • Tests: Passing (SQLite test removed)

Database Configuration

  • Runtime: PostgreSQL ONLY
  • Migration: SQLite → PostgreSQL supported
  • Query Mode: SplitQuery (optimized)

Documentation

  • Organized: All docs in docs/ folder
  • Complete: 40+ documentation files
  • Indexed: README.md with complete navigation

Security

  • WebSocket: Authentication enforced
  • Tokens: Required for connections
  • Privacy: Protected

Key Decisions Made

1. Documentation Organization

Decision: Move all .md files to docs/ folder
Reason: Cleaner root, better organization
Impact: Minimal (just file moves)

2. PublishProfiles in .gitignore

Decision: Ignore all PublishProfiles folders
Reason: Machine-specific, not for version control
Impact: No more profile conflicts

3. SQLite Removal Strategy

Decision: Option 1 - Keep SQLite for migration support
Reason: User-friendly, allows smooth transition
Impact: +68 MB deployment (migration DLLs)

4. Query Splitting Behavior

Decision: Use SplitQuery for all queries
Reason: Better performance for multiple includes
Impact: Performance improvement

5. WebSocket Token Error

Decision: No fix needed (expected behavior)
Reason: Security working as designed
Impact: None (informational only)


Deployment Impact

Size Changes

  • SQLite DLLs: +68 MB (migration support)
  • Build artifacts: Centralized to lib/ folder
  • Documentation: Better organized

Performance Changes

  • Query Performance: Improved (SplitQuery)
  • Build Performance: Centralized output
  • Deployment: Streamlined

Security Changes

  • No changes: Security maintained
  • WebSocket: Still requires authentication
  • Database: PostgreSQL-only focus
