Bruno Cadonna commented on KAFKA-9168:
--------------------------------------
Hi [~sagarrao], our internal benchmark did not show any significant performance
improvements (i.e.. throughput improvements). I left some comments on your PR.
I think the best thing to move forward here would be to implement a simple
Kafka Streams app with which you can experiment different usages of the direct
buffer for different operations on the RocksDB state stores. Then if you have
found some good use cases for the direct buffers that improve performance in
Streams, we can run our internal benchmarks again and verify if we see the
improvements also there. WDYT?
