MENTAL MODEL / KEY IDEAS

Keep these in mind

  1. 01Track state transitions
  2. 02Measure queue delay separately
  3. 03Make failures queryable
01

The job lifecycle

Enqueued, claimed, started, retried, completed, and failed are distinct states. Record them explicitly with timestamps and correlation IDs.

  • Queue latency
  • Execution time
  • Attempts
  • Terminal reason
02

Metrics and traces

Metrics show system shape; traces show one job journey. Both should use the same job and operation identifiers.

  • Throughput and lag
  • Failure rate by reason
  • End-to-end trace
03

Operator experience

A useful console answers what is stuck, whether retry is safe, and which dependency is responsible.
