zhijiangW edited a comment on issue #7438: [FLINK-11282][network] Merge StreamRecordWriter into RecordWriter URL: https://github.com/apache/flink/pull/7438#issuecomment-452584460 @pnowojski , the motivation of this PR is for fixing the issue in #7199 . To do so we can unify the `RecordWriter` implementation for both streaming and batch jobs, and make it easy for introducing new `BroadcastRecordWriter` which extends `RecordWriter` future. Although we add additional `checkErroneous` for batch mode, it should not bring performance issue I think.
