Background Workers
Offload asynchronous tasks to a separate service listening on a queue.
Background workers are services that run continuously (like a web service or a private service), but they don't receive any incoming network traffic. Instead, these services usually poll a task queue (such as one backed by a Render Key Value instance) and process new tasks as they come in:
Background workers help to keep your apps responsive by offloading long-running, asynchronous tasks from your services in the critical request path.
Common worker tasks include:
- Processing media files
- Generating reports
- Interacting with third-party APIs, such as Stripe, Twilio, or AI models
Popular worker frameworks
You can use the frameworks below to simplify polling a task queue backed by a Redis®-like store (such as Render Key Value).
