Classify errors before choosing a retry
Este artículo todavía no está disponible en Español; se muestra el original.
Use an explicit recovery table that distinguishes invalid input, access failures, transient overload and unknown write outcomes.
Contenido
Recovery policy
Use the documented API error code as well as HTTP status. Treat malformed input as a repair task and missing authorization as a permission task. Neither is helped by repeatedly sending the same request.
Suggested decision table
| Observation | Next action |
|---|---|
| Validation error | Correct the identified field and revalidate |
| Permission denied | Stop and check the authorized account and scope |
| Temporary overload | Schedule a bounded retry using service guidance |
| Timeout after sending a write | Reconcile the result before repeating the effect |
For the last case, read the operation resource or query by a documented idempotency key. A transport failure does not establish that the write failed. Only repeat a side effect when the service contract makes that repetition safe.
Acceptance fixture
Simulate a server that commits a write and then loses the connection. The client should not create a second operation merely because no success response arrived. Also test an invalid payload: its retry counter should remain zero until the payload changes.
The table is an original client policy. RFC 9110 supplies the distinction between idempotent and non-idempotent methods, not a universal retry schedule.
Alcance y fundamento
Original worked method and proposed acceptance fixtures; no empirical performance result is claimed. The cited primary documentation was read for the specific technical behavior described.
