Kenneth Knowles commented on BEAM-775:
--------------------------------------
To my understanding, aggregators and logical metrics are essentially
equivalent; metrics are just nicer to use and easier to implement. It seems
that support for aggregators - to the extent it exists in a runner - could be
ported directly to the metrics API. That is consistent with all of the intent.
> Remove Aggregators from the Java SDK
