Replay Queue

Replay Queue is where events are kept if they cannot be processed or delivered by the pipeline to the destination due to various reasons. With the replay queue, you can see all the pipelines that have failed events and address those errors by investigating the issue, replaying the event back to pipeline, or discarding it.

Stream Pipelines provides a GenAI-powered analysis that generates human-readable summaries of replay queue errors with troubleshooting recommendations.
