bq. Let me find the JIRA for the leader-to-recovering-replica that either Varun Thacker or
Tim Potter has filed.
SOLR-8225 ?

> 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.
