[jira] [Commented] (FLINK-3836) Change Histogram to enable Long counters

    [ https://issues.apache.org/jira/browse/FLINK-3836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15260255#comment-15260255 ] 

Greg Hogan commented on FLINK-3836:
-----------------------------------

{{Histogram}} is marked as part of the {{@Public}} API which can only be broken on new major releases. Could something like an equivalent {{LongHistogram}} be added instead?
