----------------------------------
Summary: Support getKey in WindowOperator.Context
Key: FLINK-14950
URL: https://issues.apache.org/jira/browse/FLINK-14950
Project: Flink
Issue Type: Improvement
Components: API / DataStream
Affects Versions: 1.9.1
Reporter: Jiayi Liao
In our scenario, user needs to access the key of {{WindowOperator.Context}} to
determine how to deal with the window.
I think it's reasonable to support {{getKey()}} method in
{{WindowOperator.Context}}.
