-----------------------------------
Summary: 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 API & SQL
Reporter: Hequn Cheng
Assignee: Hequn Cheng
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.
