ZSTD support for over-the-wire compression?

["Steinmaurer, Thomas via user" <us...@cassandra.apache.org>]

Hello,

any thoughts / reasons why ZSTD support for over-the-wire compression has been left out despite being a compression option for SSTable on-disk compression? Perhaps intentional, a technical reason behind that?

Created https://issues.apache.org/jira/browse/CASSANDRA-20488, with the main motivation having ZSTD as an option (LZ4 still as default), being internode network traffic (cost) reduction for e.g. cloud (AWS) cross-AVZ deployments, in a replication factor = number of AVZs deployment scenario, which is widely common I guess. Stefan M. on the ticket asked me to approach a mailing list to gather some feedback on that topic.

Thanks
Thomas
