Blake Eggleston commented on CASSANDRA-14482:
---------------------------------------------
[~djoshi3], I pushed up a commit
[here|https://github.com/bdeggleston/cassandra/commit/716a6b631d68532773bb804e8ce33ab3dd23946c]
that makes the following changes:
1. simplifies {{ZstdCompressor#compress}} method to just call
{{Zstd#compress}}. The compressor doesn't support on heap buffers so there's no
need to do the stream stuff. This is basically how the snappy compressor works.
2. updates test support method visibility/annotation in ZstdCompressor
3. adds ratio to CompressorPerformance output
If you're ok with these changes and I haven't broken the tests, I think this is
ready to commit.
