Summary

The text discusses the challenges of debugging Lambda function timeouts in AWS. The author shares a personal anecdote about an ex-colleague who struggled to identify the root cause of a timeout issue, highlighting that timeouts can be tricky to debug due to the lack of separate error metrics and the need for signposting IO operations. The article explores several ways to detect timeouts, including looking at Max Duration metrics, creating custom metric filters using CloudWatch, logging error messages before function timeouts, and using third-party tools like Lumigo. It also discusses finding the root cause of timeouts by analyzing logs and tracing functions with X-Ray or Lumigo. Finally, the article provides mitigation strategies for timeouts, such as timingboxing IO operations and using fallbacks, and invites readers to watch a recorded webinar on the topic.
