Matthew Biscocho commented on SOLR-17756: ----------------------------------------- Only question is whether to use the common thread pool (ForkJoinPool) or a separate dedicated thread pool. This can sometimes be a somewhat slow and heavy operation which we would not want this to be blocking the common pool. > Parallelize calculation of index fingerprint across segments > ------------------------------------------------------------ > > Key: SOLR-17756 > URL: https://issues.apache.org/jira/browse/SOLR-17756 > Project: Solr > Issue Type: Improvement > Affects Versions: main (10.0), 8.11.4, 9.8.1 > Reporter: Matthew Biscocho > Assignee: Matthew Biscocho > Priority: Major > > The index fingerprint is currently being calculated on each segment > sequentially. While this works fine, the index fingerprint calculation was > noticed to be a very slow process and on leader election is blocking. > This proposes to have this calculation parallelized across segments instead. > Since the fingerprint is just a cumulative sum of a hash on versions, the > order in which it is added to the running sum should not matter. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
