Sidekiq

Iron Laws

1. Jobs are idempotent - Safe to retry multiple times
2. Pass IDs and JSON primitives only - Never pass ORM objects
3. Enqueue after commit - Use the active ORM's commit-safe hook, not after_save or inline before commit
4. Keep queue names intentional - Operationally meaningful
5. Use retries intentionally - Don't hide permanent failures
6. Profile slow jobs - Use Sidekiq 8 profiling
7. Iterate large datasets - Use Sidekiq::Iteration
