joshelser commented on issue #661: HBASE-15519 Add per-user metrics with lossy counting URL: https://github.com/apache/hbase/pull/661#issuecomment-543765757 Just chatted with Busbey offline. @ankitsinghal is it possible to create a simple configuration property that can disable user-metrics? E.g. adding to `MetricsRegionServer`, wrapping the `MetricsUserAggregate` in an `Optional`. The thought is, we can leave this on by default, but, if in the course of some user running into performance, issues, we can easily disable just the user metrics.
