Subject [GitHub] flink pull request: [FLINK-3758] Add possibility to register accumulators in...

Github user StephanEwen commented on the pull request:

    Sorry for chiming in late.
    I was wondering whether we actually need accumulators here, or what we should add is access
to the metrics. Because the use case seems to be "monitoring", not "side aggregates".
    Admittedly, the accumulators were the means of choice for metrics up to now, but for the
future (now that we are adding proper metrics), we may want to fix this.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
