----------------------------------
Hi Jiayi,
It's an interesting ticket. Could you provide more details of your scenario?
For example,
1. Why do you need the key from context?
2. Could it be satisfied by extracting key field from element stored in window
state?
> Support getKey in WindowOperator.Context

> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Affects Versions: 1.9.1
> Reporter: Jiayi Liao
> Priority: Major
>
> 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}}.
