    Description

      With Flink 1.9 around the corner, we should consider dropping support for Flink 1.5 and 1.6.

      This 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.

      Dropping 1.5/1.6 will also decrease the build time.
