> 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.
