[GitHub] [beam] kennknowles opened a new issue, #19341: Use Flink 1.6/1.7 prepareSnapshotPreBarrier to replace BufferedOutputManager
kennknowles opened a new issue, #19341:
URL: https://github.com/apache/beam/issues/19341
Flink 1.6/1.7 provides a hook to execute an action before the snapshot barrier is emitted by the operator. At the moment (<=1.5) the Flink Runner has to buffer any elements which are emitted during a snapshot because the barrier has already been emitted. This leads to a lot of code complexity.
We can remove the buffering in favor of finishing the current bundle in `DoFnOperator`'s `prepareSnapshotPreBarrier`. The 1.5/1.6/1.7 build setup poses a challenge to do that in a way that does not lead to much code duplication.
Imported from Jira [BEAM-6733](https://issues.apache.org/jira/browse/BEAM-6733). Original Jira may contain additional context.
