Adrien Grand commented on LUCENE-6015: -------------------------------------- Hmm, correct... This explains why performance doesn't degrade for low values of the shift. > Revisit DocIdSetBuilder's heuristic to switch to FixedBitSet > ------------------------------------------------------------ > > Key: LUCENE-6015 > URL: https://issues.apache.org/jira/browse/LUCENE-6015 > Project: Lucene - Core > Issue Type: Bug > Reporter: Adrien Grand > Assignee: Adrien Grand > Priority: Minor > > DocIdSetBuilder starts with a SparseFixedBitSet and then upgrades to a > FixedBitSet when the cardinality grows larger than maxDoc >>> 14. However > Robert improved SparseFixedBitSet performance quite significantly in > LUCENE-6003 so we should see if it makes sense to update this heuristic. -- 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
