             Summary: The Overseer will batch state updates without limit.
                 Key: SOLR-5835
                 URL: https://issues.apache.org/jira/browse/SOLR-5835
             Project: Solr
          Issue Type: Improvement
          Components: SolrCloud
            Reporter: Mark Miller
            Assignee: Mark Miller
            Priority: Minor
             Fix For: 4.8, 5.0


We recently made how the Overseer processes state updates more efficient by removing a poll sleep - now, if updates come in faster than one every 100ms, the Overseer will just rip through them in a batch - but it won't update the clusterstate until done. We should only batch up to a certain number of updates or for a certain length of time before we publish the updated state so that tons of updates in the queue don't delay update visibility an unknown amount of time.
