Reliably processing messages from an SQS queue requires understanding how visibility timeouts work, how to handle failures gracefully, and how to design consumers that are idempotent. In this lesson, we dive deep into the message lifecycle and the patterns that make SQS-based systems production-ready.
Every message in SQS moves through a defined lifecycle:
[Sent] ——> [Available] ——> [In-flight] ——> [Deleted]
|
v (visibility timeout expires)
[Re-available]
The visibility timeout is the period during which a message, once received by a consumer, is invisible to all other consumers. This prevents multiple consumers from processing the same message simultaneously.
