Sidekiq & Async Patterns

Sidekiq provides built-in retry mechanisms through configuration. Set `sidekiq_retry_in` and `sidekiq_retries_exhausted` in your worker to define retry intervals and handle failures after retries are exhausted. The Skill supplies templates and patterns for robust error handling across job execution.

Idempotency ensures a job produces the same result whether executed once or multiple times. In Sidekiq, this prevents duplicate side effects when retries occur or messages reprocess. The Skill enforces idempotent design through small payloads and fail-fast behavior to guarantee reliable job execution.

Sidekiq scheduling uses `sidekiq-scheduler` or cron-like patterns defined in `sidekiq.yml`. The Skill provides configuration patterns and templates for recurring job setup, enabling you to orchestrate time-based background tasks reliably within Rails applications.

Yes, Sidekiq supports queue prioritization through multiple named queues processed with different worker counts. The Skill supplies queue configuration patterns and monitoring hooks to route high-priority jobs to dedicated workers and optimize performance across your job infrastructure.

Keep Sidekiq job payloads small—pass only IDs or minimal data, then fetch full records within the worker. The Skill enforces small payload patterns to reduce memory overhead, improve queue throughput, and prevent serialization failures in your background job system.

Sidekiq moves exhausted jobs to a dead-letter queue. The Skill implements robust death handling patterns through configuration and monitoring hooks, enabling you to inspect failed jobs, retry selectively, or log them for manual review and alerting.
