Render Background Workers

This skill explains worker services on Render: processes that consume jobs from a queue instead of serving HTTP. Pair with render-blueprints, render-env-vars, and render-networking when wiring render.yaml and private connectivity.

When to Use

• Designing or debugging queue-backed workers (Celery, Sidekiq, BullMQ, Asynq, etc.)
• Choosing between a worker, Cron Job, or Workflow for background work
• Configuring Render Key Value as a broker (not a cache) with correct eviction policy
• Implementing graceful shutdown so in-flight jobs are not lost on deploy

Per-framework setup and signal-handling detail: references/queue-framework-setup.md, references/graceful-shutdown.md.

Before deploying, restarting, or changing shutdown behavior, read references/deployments.md. Before configuring or troubleshooting a worker's outbound private-network connection, read references/private-networking.md. When choosing between a worker, cron job, and Workflow, read references/service-types.md.
