-----------------------------------------------
[~tsteinmaurer] could you hit a ML with this? Would be nice to gather as much
feedback as possible, different people have different opinions here.
> Add ZSTD support for over-the-wire compression
> ----------------------------------------------
>
> Key: CASSANDRA-20488
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20488
> Project: Apache Cassandra
> Issue Type: New Feature
> Components: Messaging/Internode
> Reporter: Thomas Steinmaurer
> Assignee: Stefan Miklosovic
> Priority: Normal
>
> Could we please consider to offer ZSTD as additional (beside LZ4) compressor
> for over-the-wire compression, if it was not intentional to not supporting
> ZSTD in messaging, beside ZSTD being supported for SSTable on-disk
> compression.
> We still could keep LZ4 as default of course when network compression is
> enabled in cassandra.yaml, but for users who want to optimize primary towards
> network traffic, this could be quite beneficial from a cost perspective when
> thinking about cloud provider (AWS) cross availability zone network traffic
> costs as the result of data replication in a setup of replication factor =
> number of racks (AVZs), as ZSTD is used to provide a better compression ratio
> compared to LZ4 at an acceptable throughput (at least in the SSTable
> department).
> Configuration-wise this could be an additional parameter in cassandra.yaml
> with LZ4 as default.
