-----------------------------------------
I'm looking at it. :-)
> Add possibility to register accumulators in custom triggers

> Priority: Minor

> 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.
