Aljoscha Krettek commented on FLINK-3758:
-----------------------------------------
[~knaufk], we might have to reconsider how this is going to work. I assume you
wanted to give access of accumulators to the Triggers to do monitoring of some
sort? If this is correct, we should probably integrate this with the new
monitoring features that [~Zentol] is currently working on.

> For monitoring purposes it would be nice to be able to to use accumulators in
> custom trigger functions.
> Basically, the trigger context could just expose {{getAccumulator}} of
> {{RuntimeContext}} or does this create problems I am not aware of?
> Adding accumulators in a trigger function is more difficult, I think, but
> that's not really neccessary as the accummulator could just be added in some
> other upstream operator.
