[jira] [Commented] (SOLR-13350) Explore collector managers for multi-threaded search

["Ishan Chattopadhyaya (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-13350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17735331#comment-17735331 ] 

Ishan Chattopadhyaya commented on SOLR-13350:
---------------------------------------------

I've updated the patches here to latest main and 9x:
https://github.com/chatman/solr/tree/jira/solr-13350-5
https://github.com/chatman/solr/tree/jira/solr-13350-9x

Did a performance testing on this suite: https://github.com/fullstorydev/solr-bench/blob/master/suites/stress-facets-local.json
Querying performance is about 24x slower! :-o Seems like some obvious bottleneck, that I'll be working on chasing down.

> AFAICT, SolrIndexSearcher can be used only to search all the segments of an index in series. However, using CollectorManagers, segments can be searched concurrently and result in reduced latency. Opening this issue to explore the effectiveness of using CollectorManagers in SolrIndexSearcher from latency and throughput perspective.
