ASF subversion and git services commented on SOLR-11522: -------------------------------------------------------- Commit 576d28f643a89de832b59a783ce729402d70fb9f in lucene-solr's branch refs/heads/master from noble [ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=576d28f ] SOLR-11522: Moved the _get methods to a separate interafce and keep MapWriter clean > Suggestions/recommendations to rebalance replicas > ------------------------------------------------- > > Key: SOLR-11522 > URL: https://issues.apache.org/jira/browse/SOLR-11522 > Project: Solr > Issue Type: Sub-task > Security Level: Public(Default Security Level. Issues are Public) > Components: AutoScaling > Reporter: Noble Paul > Priority: Major > > It is possible that a cluster is unbalanced even if it is not breaking any of > the policy rules. Some nodes may have very little load while some others may > be heavily loaded. So, it is possible to move replicas around so that the > load is more evenly distributed. This is going to be driven by preferences. > The way we arrive at these suggestions is going to be as follows > # Sort the nodes according to the given preferences > # Choose a replica from the most loaded node ({{source-node}}) > # try adding them to the least loaded node ({{target-node}}) > # See if it breaks any policy rules. If yes , try another {{target-node}} > (go to #3) > # If no policy rules are being broken, present this as a {{suggestion}} . > The suggestion contains the following information > #* The {{source-node}} and {{target-node}} names > #* The actual v2 command that can be run to effect the operation > # Go to step #1 > # Do this until the a replicas can be moved in such a way that the {{target > node}} is more loaded than the {{source-node}} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
