Jark Wu closed FLINK-11203.
---------------------------
Resolution: Fixed
We implemented a window operator for table in blink planner which supports to
expose metrcis, so we don't have this problem.
> FunctionContext of AggregateFunction will not be initialized for window
> GroupBy

> Key: FLINK-11203
> URL: https://issues.apache.org/jira/browse/FLINK-11203
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Hequn Cheng
> Priority: Major
> Labels: auto-unassigned
>
> Currently, in tableApi/SQL, the implementable of aggregation of group window
> is base on the WindowStream and
> {{org.apache.flink.api.common.functions.AggregateFunction}}.
> Due to FLINK-11198, metrics cannot be accessed within
> {{org.apache.flink.table.functions.AggregateFunction}} either. It would be
> nice if we support metrics for both of them.
