Subject [jira] [Commented] (ACCUMULO-4500) Implement visibility histograms as a table feature
Date Mon, 17 Oct 2016 12:57:58 GMT


Keith Turner commented on ACCUMULO-4500:

I am in favor of making a configurable per table function.  The function would take in key
values and emit counts.  The emitted counts would build the histogram.   Not configuring a
function would turn it off.  General counts could be used by compaction strategies when making
decisions.  This would be useful for ACCUMULO-1266.
