Jark Wu commented on FLINK-14274:
---------------------------------
I agree with [~ykt836], we can definitely add more reasonable methods in
FunctionContext, but state methods is not one of them.
For example, adding methods for taskName and taskIndex and configurations make
sense to me.
> RuntimeContext can be get from FunctionContext
