symfony:messenger-retry-failures

Configure Symfony Messenger retries with exponential backoff by defining custom retry logic that delays failed messages with increasing intervals. This Skill implements these configurable retry strategies to stabilize critical background tasks until successful or moved to a failed queue.

Idempotency in asynchronous message handling ensures handlers execute safely multiple times without unintended side effects. You need idempotent handlers when implementing at-least-once delivery semantics, which guarantees deterministic processing even if messages are retried.

Set up a Symfony Messenger failure transport by configuring a dedicated transport to isolate poison-messages. This Skill provides operational visibility and tools for inspecting and reprocessing these failed background tasks for manual intervention.

Yes, this approach to async workflow resilience works for temporary gateway timeouts. It automatically retries the failed message with increasing delays until successful, satisfying at-least-once delivery requirements for critical background tasks.

The best way to monitor Symfony Messenger message processing failures is to configure operational visibility over a dedicated failure transport. This Skill provides the necessary tools for robust monitoring, inspection, and reprocessing of failed messages.
