             Summary: In cloud mode the leader should distribute autoCommits to it's replicas
                 Key: SOLR-6606
                 URL: https://issues.apache.org/jira/browse/SOLR-6606
             Project: Solr
          Issue Type: Improvement
            Reporter: Varun Thacker
             Fix For: 5.0, Trunk


Today in SolrCloud different replicas of a shard can trigger auto (hard) commits at different times. Although the documents which get added to the system remain consistent the way the segments gets formed can be different because of this.

The downside of segments not getting formed in an identical fashion across replicas is that when a replica goes into recovery chances are that it has to do a full index replication from the leader. This is time consuming and we can possibly avoid this if the leader forwards auto (hard) commit commands to it's replicas and the replicas never explicitly trigger an auto (hard) commit.

I am working on a patch. Should have it up shortly
