Subject [jira] [Commented] (SOLR-10528) Use docvalue for range faceting in JSON facet API
Date Thu, 20 Apr 2017 00:47:04 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15975826#comment-15975826

Yonik Seeley commented on SOLR-10528:
-------------------------------------

Yep, we should definitely do this.  Perhaps use method=dv/enum to force one method over the
other, and otherwise try to pick the best method based on the data.

> Range faceting in JSON facet API has only one implementation. In the implementation,
all buckets are allocated and then range queries are executed for all the buckets. Therefore,
memory usage and computational cost of range facet can be very high if range is wide and gap
is narrow. 
> I think range faceting in JSON facet should have the implementation which uses DocValues
instead of inverted indices. By scanning DocValues, we can execute range facets much more
efficiently especially when the number of buckets is large.
