> LZ4 is generally faster than Snappy. That's probably we use LZ4 in changelogs
> and other places by default. However, we don't change RocksDB's default of
> Snappy compression style. The RocksDB Team recommend LZ4 or ZSTD and the
> default is kept to Snappy only for backward compatible reason. We should use
> LZ4 instead.
