[jira] [Commented] (ACCUMULO-4501) Add support to RFile to track
and store the histogram
[ https://issues.apache.org/jira/browse/ACCUMULO-4501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15581160#comment-15581160 ]
Josh Elser commented on ACCUMULO-4501:
--------------------------------------
Initial wag at an implementation. https://github.com/apache/accumulo/pull/168
*Very* much a work-in-progress.
* Histogram implementation is very naive
* Lots of making internally classes public instead of adding to 1k+ LOC files
* Some simple tests which show basic correctness
Feedback on approach welcome. Will be a nights+weekends thing, so I will not be super responsive on this.

> Reading the RFile would deserialize the histogram back into memory.
