------------------------------

             Summary: Flink Hudi Support Commit on empty batch 
                 Key: HUDI-6127
                 URL: https://issues.apache.org/jira/browse/HUDI-6127
             Project: Apache Hudi
          Issue Type: New Feature
          Components: flink
            Reporter: Qijun Fu


In flink multi-writer scenario, if one of the writers has no data, it will keep 
its inflight instant in the timeline. But incremental clean and archive will be 
blocked by the oldest inflight commit in the timeline.

So to make clean and archive can move forward  we should upport starting a new 
instant even when there is no data in the last batch.
