> In our production environment, we prefer to use LZ4 instead of Snappy as compression for better performance, which is also [recommended by RocksDB |https://github.com/facebook/rocksdb/wiki/Compression#configuration].
> I plan to introduce LZ4 except for now existing snappy compression for keyed state in full checkpoint and savepoints.
