Context

get_db_client() in auth.py instantiates a new DatabaseClient on every call. This bypasses any connection pooling logic and can exhaust available database connections under concurrent load.

Roadmap reference: ROADMAP.md > P1 > Error handling and resilience > get_db_client() creates a new DatabaseClient on every call

What to do

  1. Identify the existing connection pool or pooled client used elsewhere in the application (e.g., in database.py or the FastAPI lifespan context).
  2. Refactor get_db_client() (or replace it with a FastAPI dependency) to yield the shared pooled client instead of creating a new one.
  3. Ensure the client is properly released/returned to the pool after each request.
  4. Add or update tests to verify no new DatabaseClient instances are created per-request.

Acceptance criteria

  • A single DatabaseClient (or pool) is created at application startup.
  • Auth routes consume connections from the shared pool.
  • Under a basic load test (e.g., 20 concurrent login requests) the application does not raise connection-limit errors.
