Thanks a lot for sharing the good results.
As investigated by Wes, we have existing zstd library for Java (zstd-jni)
[1], and lz4 library for Java (lz4-java) [2].
+1 for the 1024 batch size, as it represents an important scenario where
the batch fits into the L1 cache (IMO).
Best,

I just took a first pass at reviewing the Java and Rust issues and removed
some from the 0.17.0 release. There are a few small Rust issues that I am
actively working on for this release.
Thanks.

hi Neal,
Thanks for helping coordinate. I agree we should be in a position to
release sometime next week.
Can folks from the Rust and Java side review issues in the backlog?
According to the dashboard there are 19 Rust issues open and 7 Java
issues.
Thanks

If it isn't hard could you run with batch sizes of 1024 or 2048 records? I
think there was a question previously raised if there was benefit for
smaller sizes buffers.
Thanks,
Micah
