Emmanuel Keller created LUCENE-7588: ---------------------------------------
Summary: A parallel DrillSideways implementation Key: LUCENE-7588 URL: https://issues.apache.org/jira/browse/LUCENE-7588 Project: Lucene - Core Issue Type: Improvement Affects Versions: master (7.0), 6.3.1 Reporter: Emmanuel Keller Priority: Minor Fix For: master (7.0), 6.3.1 Currently DrillSideways implementation is based on the single threaded IndexSearcher.search(Query query, Collector results). On large document set, the single threaded collection can be really slow. The ParallelDrillSideways implementation could: 1. Use the CollectionManager based method IndexSearcher.search(Query query, CollectorManager collectorManager) to get the benefits of multithreading on index segments, 2. Compute each DrillSideway subquery on a single thread. -- 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
