Satish Duggana resolved KAFKA-14993.
------------------------------------
Resolution: Fixed
> Improve TransactionIndex instance handling while copying to and fetching from
> RSM.
> ----------------------------------------------------------------------------------
>
> Key: KAFKA-14993
> URL: https://issues.apache.org/jira/browse/KAFKA-14993
> Project: Kafka
> Issue Type: Improvement
> Components: core
> Reporter: Satish Duggana
> Assignee: Abhijeet Kumar
> Priority: Blocker
> Labels: tiered-storage
> Fix For: 3.6.0
>
>
> RSM should throw a ResourceNotFoundException if it does not have
> TransactionIndex. Currently, it expects an empty InputStream and creates an
> unnecessary file in the cache. This can be avoided by catching
> ResourceNotFoundException and not creating an instance. There are minor
> cleanups needed in RemoteIndexCache and other TransactionIndex usages.
> Also, update the LocalTieredStorage, see
> [this|https://github.com/apache/kafka/pull/13837#discussion_r1258917584]
> comment.
> Note, please remember to update the javadoc in RSM after the fix. See:
> https://github.com/apache/kafka/pull/14352
