Filtering would be a good feature to add. I have also been trying to gather
some opinion on in-process aggregation at component level, without much success
:) Codahale metric registry is a great alternative but that would translating
many metrics in the storm-core to codahale compliant implementations e.g.
CountMetric to Counter. I am willing to spend that effort if approach sounds
good.
