----------------------------------------------
Assignee: A. Sophie Blee-Goldman
> Kafka Streams should commit transaction when no records are processed
> ---------------------------------------------------------------------
>
> Key: KAFKA-14294
> URL: https://issues.apache.org/jira/browse/KAFKA-14294
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Affects Versions: 3.2.1
> Reporter: Vicky Papavasileiou
> Assignee: A. Sophie Blee-Goldman
> Priority: Major
>
> Currently, if there are no records to process in the input topic, a
> transaction does not commit. If a custom punctuator code is writing to a
> state store (which is common practice) the producer gets fenced when trying
> to write to the changelog topic. This throws a TaskMigratedException and
> causes a rebalance.
> A better approach would be to commit a transaction even when there are no
> records processed as to allow the punctuator to make progress.
