Resolution: Duplicate
> Options for handling exceptions during processing
> -------------------------------------------------
>
> Key: KAFKA-5158
> URL: https://issues.apache.org/jira/browse/KAFKA-5158
> Project: Kafka
> Issue Type: Task
> Components: streams
> Reporter: Eno Thereska
> Priority: Major
>
> Imagine the app-level processing of a (non-corrupted) record fails (e.g. the
> user attempted to do a RPC to an external system, and this call failed). How
> can you process such failed records in a scalable way? For example, imagine
> you need to implement a retry policy such as "retry with exponential
> backoff". Here, you have the problem that 1. you can't really pause
> processing a single record because this will pause the processing of the full
> stream (bottleneck!) and 2. there is no straight-forward way to "sort" failed
> records based on their "next retry time".
