> As discussed in [ML thread|https://s.apache.org/us0en], we decided to increase the default value of `state.backend.fs.memory-threshold` from 1K to *20K* to prevent too many small files created on remote FS.
> We need to add an explicit release note to notify our users about this change, especially for those having jobs with large parallelism on source or stateful operators.
