Aljoscha Krettek commented on FLINK-3758:
-----------------------------------------
There might be one, I don't know too much about it, unfortunately. Maybe
[~Zentol] or [~rmetzger] could help us with that.
About whether it will replace the accumulators, I'm not sure. For me the
accumulators always seemed the right tool for monitoring so maybe they will be
replaced by something better and then be deprecated at some point.
[~StephanEwen] and I recently had a short discussion about that, maybe he'd
also like to chime in on this.

> 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.
