> At present, there is no information about userKeySeriailzer in org.apache.link.runtime.state.v2.RegisteredKeyValueStateBackendMetaInfo.
> If MapState is used and the schema of userKey has changes, StateBackend cannot determine if it is compatible. So we need to add the information of userKeySeriailzer in org.apache.link.runtime.state.v2.RegisteredKeyValueStateBackendMetaInfo
