> Currently, the {{FsStateBackend}} writes all state into files. Some state (like Kafka Offsets) is so small that it adds unnecessary overhead, and sometimes the checkpointed file handles are larger than the actual state.
> Small state (below a certain threshold, say 1 KB) should not be stored in files, but directly in the state handles.
