Aljoscha Krettek commented on FLINK-20337: ------------------------------------------ It's not incomplete, it's just that existing users of the {{StreamingFileSink}} cannot migrate. This doesn't have to be a blocker. We can add it whenever it's ready and ship it in a point release. > 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 > Assignee: Guowei Ma > Priority: Blocker > Fix For: 1.12.0 > > > 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 provide a way for the user who uses `StreamingFileSink` to migrate > from `StreamingFileSink` to `FileSink`. > For this purpose we propose to let the new sink writer operator could load > the previous StreamingFileSink's state and then the `SinkWriter` could have > the opertunity to handle the old state. > -- This message was sent by Atlassian Jira (v8.3.4#803005)
