> GroupWindow and OverWindow aggregates do not check correctly for updating
> input
> -------------------------------------------------------------------------------

> Key: FLINK-7239
> URL: https://issues.apache.org/jira/browse/FLINK-7239
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.3.1, 1.4.0
> Reporter: Fabian Hueske
> Priority: Major
> Labels: stale-major
>
> The streaming table operators for group-window and over-window aggregates do
> only support append-only input, i.e., no updates.
> However, the {{DataStreamGroupWindowAggregate}} {{DataStreamOverAggregate}}
> RelNodes do only check that the input does not have retraction messages which
> is only one possible encoding of updates.
> We should fix the RelNodes to check if the input is append-only using the
> {{UpdatingPlanChecker}} similar to {{DataStreamWindowJoin}}.
