Hoss Man updated SOLR-6968: --------------------------- Attachment: SOLR-6968_nosparse.patch patch that worked well in my perf tests to disable SPARSE (and optimize some ram usage when merging EMPTY) ... will commit once {{ant precommit test}} finishes. > add hyperloglog in statscomponent as an approximate count > --------------------------------------------------------- > > Key: SOLR-6968 > URL: https://issues.apache.org/jira/browse/SOLR-6968 > Project: Solr > Issue Type: Sub-task > Reporter: Hoss Man > Assignee: Hoss Man > Fix For: Trunk, 5.2 > > Attachments: SOLR-6968.patch, SOLR-6968.patch, SOLR-6968.patch, > SOLR-6968.patch, SOLR-6968.patch, SOLR-6968.patch, SOLR-6968_nosparse.patch > > > stats component currently supports "calcDistinct" but it's terribly > inefficient -- especially in distib mode. > we should add support for using hyperloglog to compute an approximate count > of distinct values (using localparams via SOLR-6349 to control the precision > of the approximation) -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
