Exercise

Throttle background ingestion tasks with backpressure

Implement this task with explicit validation, predictable output shape, and enough error handling that it could survive reuse in a real AI workflow.

Api Async / hard / Step 5 of 23

Practice stage

Async and provider control

Hint

Make waiting behavior explicit. Timeouts, retries, and concurrency limits matter more than squeezing everything into one helper.

Next drill
Retry only idempotent ingestion steps
Success criteria
  • - Uses async boundaries coherently
  • - Makes timeout and retry decisions legible
  • - Would be maintainable under provider instability
Review checklist
  • - Is timeout behavior explicit?
  • - Is retryable failure separate from terminal failure?
  • - Would logs reveal what actually timed out?
