Ignacio Vera created LUCENE-8562: ------------------------------------ Summary: Speed up merging segments of points with data dimensions Key: LUCENE-8562 URL: https://issues.apache.org/jira/browse/LUCENE-8562 Project: Lucene - Core Issue Type: Improvement Components: core/index Affects Versions: master (8.0), 7.7 Reporter: Ignacio Vera
Currently when merging segments of points with data dimensions, all dimensions are sorted and carried over down the tree even though only indexing dimensions are needed to build the BKD tree. This is needed so leaf node data can be compressed by common prefix. But when using _MutablePointValues_, this ordering is done at the leaf level so we can se a similar approach from data dimensions and delay the sorting at leaf level. This seems to speed up indexing time as well as reduce the storage needed for building the index. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
