Description:
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.
