Sorry for the delayed response. I missed your comments.
I haven't had a chance to look deeply into the code yet, so I'm afraid it would
be difficult for me to provide much concrete help at this point.
Are you planning to continue working on this? If not, and if you're okay with
it, I'd be happy to take it over, look into it more deeply, and then ask you
for a review.
> Optimize retry backoff for CONCURRENT_TRANSACTIONS to improve TV2 throughput
> ----------------------------------------------------------------------------
>
> Key: KAFKA-20000
> URL: https://issues.apache.org/jira/browse/KAFKA-20000
> Project: Kafka
> Issue Type: Improvement
> Reporter: Chia-Ping Tsai
> Assignee: Francis Godinho
> Priority: Major
> Fix For: 4.5.0
>
>
> Transaction V2 introduces frequent state transitions (epoch bumps) that
> briefly reject concurrent requests with CONCURRENT_TRANSACTIONS. The default
> client retry backoff (100ms) is excessive for these transient locks, leading
> to unnecessary latency and degraded throughput. Reducing the backoff allows
> faster retries and smoother performance during state transitions.
