[jira] [Created] (FLINK-21467) Document possible recommended usage of Bounded{One/Multi}Input.endInput and emphasize that they could be called multiple times

Kezhu Wang created FLINK-21467:
----------------------------------

             Summary: Document possible recommended usage of Bounded{One/Multi}Input.endInput and emphasize that they could be called multiple times
                 Key: FLINK-21467
                 URL: https://issues.apache.org/jira/browse/FLINK-21467
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
    Affects Versions: 1.13.0
            Reporter: Kezhu Wang


It is too tempting to use these api, especially {{BoundedOneInput.endInput}}, to commit final result before FLIP-147 delivered. And this will cause re-commit after failover as [~gaoyunhaii] has pointed out in FLINK-21132.

I have [pointed|https://github.com/apache/iceberg/issues/2033#issuecomment-784153620] this out in [apache/iceberg#2033|https://github.com/apache/iceberg/issues/2033], please correct me if I was wrong.
