merged 4f7725aa into master which is not blocked by the performance result.
I also think it's worthy discussing and we could find a better default

> Currently, RocksDBStateBackend does not support setting the compression
> level, and Snappy is used for compression by default. But we have some
> scenarios where compression will use a lot of CPU resources. Turning off
> compression can significantly reduce CPU overhead. So we may need to support
> a parameter for users to set the CompressType of Rocksdb.
