[jira] [Commented] (SOLR-5748) Introduce autoIncreaseReplicas collection property

["Mark Miller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-5748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13905616#comment-13905616 ] 

Mark Miller commented on SOLR-5748:
-----------------------------------

Something that also decreases replicas makes more sense to me. If ZK is the truth, ZK knows how many replicas there should be. If there are too many because you put some old downed servers back in rotation, or if there are not enough, it seems like the cluster should react the same way - adjust to the user specified number of replicas if possible while meeting other parameters: maxShardsPerNode, available nodes, etc.

> I propose to introduce a collection property called autoIncreaseReplicas. This will be used only with the ZK as truth mode. If set to true, then whenever the number of replicas for a shard fall below the replicationFactor and the down nodes do not come back up for a configurable amount of time, additional replicas will be started up automatically.
