Subject [jira] [Commented] (SOLR-8227) Recovering replicas should be able to recover from any active replica
Date Fri, 06 Nov 2015 23:44:10 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14994723#comment-14994723

Timothy Potter commented on SOLR-8227:
--------------------------------------

one question that comes to mind is what happens if the replica I'm recovering from goes into
recovery? I guess a related question is what happens today if the leader changes?

> Currently when a replica goes into recovery it uses the leader to recover. It first 
 tries to do a PeerSync. If thats not successful it does a replication. Most of the times
it ends up doing a full replication because segment merging, autoCommits causing segments
to be formed differently on the replicas ( We should explore improving that in another issue
) . 
> But when many replicas are recovering and hitting the leader, the leader can become a
bottleneck. Since Solr is a CP system , we should be able to recover from any of the 'active'
replicas instead of just the leader.
