Mikhail Khludnev commented on LUCENE-9328: ------------------------------------------ [~romseygeek], you are welcome [https://github.com/apache/lucene-solr/pull/1462/] At the patch all type docvalues pooled already. I'm not sure I understand what you mean in _control advancing the iterators_. Now there's no control. It's not so scary as it looked at the first glance. Collector scores docs in-order (o'rlly?), every doc just kicks a certain GroupHead, which pull a value(s) from it. And that's it. I don't even think they ever call dv.advanceExact() for the current dv.docID. I think I'll add a test covering grouping/sorting over sortedset dvs. > SortingGroupHead to reuse DocValues > ----------------------------------- > > Key: LUCENE-9328 > URL: https://issues.apache.org/jira/browse/LUCENE-9328 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/grouping > Reporter: Mikhail Khludnev > Assignee: Mikhail Khludnev > Priority: Minor > Attachments: LUCENE-9328.patch, LUCENE-9328.patch, LUCENE-9328.patch > > Time Spent: 10m > Remaining Estimate: 0h > > That's why > https://issues.apache.org/jira/browse/LUCENE-7701?focusedCommentId=17084365&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17084365 -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
