[jira] [Commented] (SOLR-3583) Percentiles for facets, pivot
facets, and distributed pivot facets
[ https://issues.apache.org/jira/browse/SOLR-3583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14091564#comment-14091564 ]
Hoss Man commented on SOLR-3583:
--------------------------------
FWIW: I haven't spent a lot of time looking at this patch, but from what i've seen of the syntax for requesting percentiles, it seemed kind of cumbersome to me.
I've opened a couple of issues (SOLR-6350 & SOLR-6351) which i think could give us all the functionality described here -- plus a lot more flexibility through a more general mechanism of computing stats per pivot.
I also think that in general, leveraging the "tdigest" library to do distributed percentiles seems like better idea then reinventing the wheel ourselves.
