> Key: BEAM-9838
> URL: https://issues.apache.org/jira/browse/BEAM-9838
> Project: Beam
> Issue Type: Bug
> Components: runner-flink
> Affects Versions: 2.18.0, 2.19.0, 2.20.0
> Reporter: David Neth
> Priority: P3
>
> The Flink runner doesn't seem to be advancing the offset for splittable DoFns. Using a non-splittable DoFn results in the watermark advancing, as does using the direct runner.
>
> I started a conversation on the mailing list that has more detail:

>
> This behavior has been observed on beam 2.18, 2.19 and 2.20 and Flink 1.8.
