             Summary: Make migrate `StreamingFileSink` to `FileSink` possible
                 Key: FLINK-20337
                 URL: https://issues.apache.org/jira/browse/FLINK-20337
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
    Affects Versions: 1.12.0
            Reporter: Guowei Ma


Flink-1.12 introduces the `FileSink` in FLINK-19510, which can guarantee the exactly once semantics both in the streaming and batch execution mode.

We need to figure out how to migrate from `StreamingFileSink` to `FileSink` for the user who uses the `StreamingFileSink` currently.

 

The pr wants provide a way that make it possible.
