Resiliency

Production resilience with retries, dead letter, outbox, and deduplication

Works with: Laravel, Symfony, and Standalone PHP

The Problem

A failed HTTP call crashes your handler. A duplicate webhook triggers double-processing. You've wrapped handlers in try/catch blocks and retry loops — each one slightly different. Error handling is scattered across your codebase with no consistent strategy.

How Ecotone Solves It

Ecotone handles failures at the messaging layer — not per feature. Automatic retries, error channels, dead letter queues, the outbox pattern, and idempotency are configured once and apply to all handlers on a channel. When something fails, messages are preserved and can be replayed after the bug is fixed.

Explore the resiliency features:

• Retries — Automatic retry strategies for transient failures
• Error Channel and Dead Letter — Store failed messages for later replay
• Final Failure Strategy — What happens when all retries are exhausted
• Idempotency (Deduplication) — Prevent double-processing
• Resilient Sending — Guaranteed delivery to async channels
• Outbox Pattern — Atomic message publishing with database transactions
• Concurrency Handling — Optimistic and pessimistic locking
