[BEAM-7962] Drop support for Flink 1.5 and 1.6 - #9632
Merged
Conversation
Flink 1.9 is now released and Beam 2.17.0 is going to support it. Since the Flink community only supports the last two Flink releases, it is now time to drop at least 1.5 and 1.6. As a follow-up, we will get rid of Flink 1.5/1.6 specific workarounds, e.g. make use of Flink's preSnapshotBarrier in AbstractStreamOperator which removes the needs to buffer elements during a snapshot. Build time should decrease by several minutes.

Nice, great to see the simplification this brings (and the reduction in CI burden).

…OutputManager For Flink version <= 1.5 the Flink Runner had to buffer any elements which are emitted during a snapshot because the barrier has already been emitted. Flink version >= 1.6 provides a hook to execute an action before the snapshot barrier is emitted by the operator. We can remove the buffering in favor of finishing the current bundle in the DoFnOperator's prepareSnapshotPreBarrier. This had previously been deferred (apache#7940) until removal of Flink 1.5 (apache#9632).
