Using zstd compression on Cassandra 3.x

Hi all,

Since zstd compression is a very good compression algorithm, it is available in Cassandra 4.0. Because the overall performance and ratio are excellent

There is open source available for Cassandra 3.x.
https://github.com/MatejTymes/cassandra-zstd

Do you have any experience applying this to production?

I want to improve performance and disk usage by applying it to a running Cassandra cluster.

Thanks.

I patched this on 3.11.2 easily: 

1. build jar file from src and put in cassandra/lib directory

2. restart cassandra service

3. alter table using compression zstd and rebuild sstables



But it was in a time when 4.0 was not available yet and after that i upgraded to 4.0 immidiately.

Thank you for your response.

I'll consider upgrading to 4.x.

Is there something preventing you from upgrading to 4.0? It is backward compatible with 3.0 so clients don’t need to change.

If you don’t want to absolutely upgrade you can extract the implementation from 4.0 and use it. I would advise against this path though as zstd implementation is nuanced.
