> 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.
