Francis Godinho commented on KAFKA-20000:
-----------------------------------------
Reading the thread, I think introducing 2 new configs make sense. It solves the
unnecessarily long backoff, but also addresses the system dependent aspect.
[~chia7712], are you planning on implementing this? I would love to take a stab
it otherwise!
> Optimize retry backoff for CONCURRENT_TRANSACTIONS to improve TV2 throughput

>
> 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.
