> Right now, we only have a {{StateBackendFactory}} for the {{FsStateBackend}} which means that users cannot specify to use the RocksDB backend in the flink configuration.
> If we add a factory for rocksdb we should also think about adding the rocksdb backend to the standard distribution lib, otherwise it is only usable if users manually place the rocks jars in the Flink lib folder.
