-----------------------------------
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
