fail
> Add group-windows for streaming tables
> ---------------------------------------
>
> Key: FLINK-4691
> URL: https://issues.apache.org/jira/browse/FLINK-4691
> Project: Flink
> Issue Type: Sub-task
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Timo Walther
>
> Add Tumble, Slide, Session group-windows for streaming tables as described in
> [FLIP-11|https://cwiki.apache.org/confluence/display/FLINK/FLIP-11%3A+Table+API+Stream+Aggregations].
>
> Implementation of group-windows on streaming tables. This includes
> implementing the API of group-windows, the logical validation for
> group-windows, and the definition of the “rowtime” and “systemtime” keywords.
> Group-windows on batch tables won’t be initially supported and will throw an
> exception.
