Just for clarity here, I'll eat my words (the benchmark was modified to make them comparable) and we are still discussing (I think this is another case of gRPC/Java's long standing issue with a small fixed backpressure threshold). On Fri, Aug 26, 2022, at 07:43, David Li wrote: > I replied on Gi

I replied on Github, but in short, the two benchmarks aren't measuring anything remotely near the same thing. They are not comparable at all. The Java version could use work to be on par with the C++ version. It does report figures in a misleading way. On Fri, Aug 26, 2022, at 06:04, Игорь Скок

Hello, I created the issue https://github.com/apache/arrow/issues/13980 with a question about the performance difference of Arrow Flight C++ and Java. Will be glad to hear suggestions from you Thanks
