> 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.
