Andrzej Bialecki created SOLR-15209: ---------------------------------------
Summary: Make the AffinityPlacementFactory the default placement plugin Key: SOLR-15209 URL: https://issues.apache.org/jira/browse/SOLR-15209 Project: Solr Issue Type: Improvement Security Level: Public (Default Security Level. Issues are Public) Reporter: Andrzej Bialecki 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 (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
