>             Project: Beam
>          Issue Type: Bug
>          Components: runner-flink
>            Reporter: Maximilian Michels
>            Assignee: Maximilian Michels
>            Priority: Major
>             Fix For: 2.16.0
>
>
> 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.
