> Key: KAFKA-19760
> URL: https://issues.apache.org/jira/browse/KAFKA-19760
> Project: Kafka
> Issue Type: Bug
> Components: group-coordinator
> Affects Versions: 4.0.0, 4.1.0
> Reporter: Sean Quah
> Assignee: Izzy Harker
> Priority: Blocker
> Fix For: 4.2.0, 4.0.2, 4.1.1

>
> The coordinator runtime can be overly optimistic about compression ratios
> when filling up batches and can often overflow `max.message.bytes` of the
> topic. When this happens, all the group coordinator requests that wrote to
> the batch fail with an UNKNOWN_SERVER_ERROR. This error is non-retriable and
> disruptive to client applications.
