Eno Thereska created KAFKA-5158: ----------------------------------- Summary: Options for handling exceptions during processing Key: KAFKA-5158 URL: https://issues.apache.org/jira/browse/KAFKA-5158 Project: Kafka Issue Type: Sub-task Components: streams Reporter: Eno Thereska
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". -- This message was sent by Atlassian JIRA (v6.3.15#6346)
