Zach Chen commented on LUCENE-9662: ----------------------------------- Hi [~mikemccand], I've taken a stab at this and created a WIP PR [https://github.com/apache/lucene/pull/128] with some nocommit comments. Could you please take a look and let me know your thoughts? > CheckIndex should be concurrent > ------------------------------- > > Key: LUCENE-9662 > URL: https://issues.apache.org/jira/browse/LUCENE-9662 > Project: Lucene - Core > Issue Type: Bug > Reporter: Michael McCandless > Priority: Major > > I am watching a nightly benchmark run slowly run its {{CheckIndex}} step, > using a single core out of the 128 cores the box has. > It seems like this is an embarrassingly parallel problem, if the index has > multiple segments, and would finish much more quickly on concurrent hardware > if we did "thread per segment". > If wanted to get even further concurrency, each part of the Lucene index that > is checked is also independent, so it could be "thread per segment per part". -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
