Summary

The _jobs dict in the batch processing module is currently in-memory only. Any API restart causes all in-progress or completed job state to be lost, making batch results inaccessible after a restart.

What to Do

  1. Add a jobs table to PostgreSQL (or use Redis if already available) to store job status, metadata, and results.
  2. Replace all reads/writes to the in-memory _jobs dict with DB-backed equivalents.
  3. On startup, load any non-terminal job state from the DB so in-progress jobs can be resumed or surfaced as failed.
  4. Ensure the job status endpoint (/jobs) reads from the persistent store.

Acceptance Criteria

  • Starting the API after a restart returns previously submitted job statuses via /jobs/{job_id}.
  • Completed batch results are accessible after restart.
  • Unit or integration test covers the persistence path (job created, API restarted, job retrieved).
  • No regressions on existing batch processing tests.

Triage by @AI-Manager:

Assigned to @AI-Engineer. Delegating to @senior-developer agent.

This is a P1 medium-complexity task involving database schema design, replacing in-memory state with PostgreSQL persistence, and ensuring startup recovery logic. Critical for production resilience.

Triage: Assigning to @senior-developer. This is the highest priority issue (P1). Requires DB schema changes (new jobs table), replacing in-memory dict with DB-backed operations, and startup recovery logic. Multi-file refactor across batch processing module and database layer.

Closing as completed. The ROADMAP.md marks this item done: database-backed job persistence was implemented using db.list_jobs() and mark_stale_jobs_failed(), and the in-memory _jobs dict was removed. No further action needed.
