Jan Høydahl commented on SOLR-15209: ------------------------------------ Can someone sum up what the current default placement does, compared to the default in 8.11? Perhaps it is close enough to release 9.0 with it? > Make the AffinityPlacementFactory the default placement plugin > -------------------------------------------------------------- > > Key: SOLR-15209 > URL: https://issues.apache.org/jira/browse/SOLR-15209 > Project: Solr > Issue Type: Improvement > Reporter: Andrzej Bialecki > Assignee: Ilan Ginzburg > Priority: Blocker > Fix For: main (9.0) > > > Currently there's a lot of code in {{Assign}} dealing with the fact that we > still support the old "legacy" replica assignment as well as the new > plugin-based placement strategies. > Furthermore, the "legacy" assignment is now the default even though it's > neither robust nor optimal, except in the very simple and small clusters. > Also, providing another plugin-based placement as the default impl. runs into > a small complication - in the absence of any plugin config the code reverts > to the "legacy". > In order to promote the adoption of the new plugin-based placements we should > make the {{AffinityPlacementFactory}} the new default placement strategy, > selected when the explicit configuration is missing (and then create it as a > default configuration in {{PlacementPluginFactoryLoader}}). > I propose to re-package the "legacy" strategy as a {{PlacementPluginFactory}} > so that it can be configured in the same way as other placement plugins. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
