Context

Roadmap item: P1 - Error handling and resilience

get_db_client() in auth.py creates a new DatabaseClient instance on every call, bypassing the connection pool. Under load this can exhaust available database connections.

What to do

  • Refactor auth.py to share a single DatabaseClient instance (or dependency-inject the existing pooled client used elsewhere in the app)
  • Use FastAPI dependency injection (Depends) to pass the shared DB client into auth endpoints
  • Ensure the client is properly closed on application shutdown

Acceptance criteria

  • get_db_client() no longer instantiates a new client on every call
  • Auth endpoints receive the same pooled client as other endpoints
  • Load test or code review confirms connection count is bounded
  • No regression in auth functionality

Triage: Already Resolved

The get_db_client() function in SPARC/auth.py (line 168) returns a module-level singleton DatabaseClient that uses ThreadedConnectionPool from psycopg2 (defined in SPARC/database.py). No per-request connection creation.

Closing as resolved.
