[jira] [Created] (SOLR-8707) Distribute commit requests evenly

Michael Sun created SOLR-8707:
---------------------------------

             Summary: Distribute commit requests evenly
                 Key: SOLR-8707
                 URL: https://issues.apache.org/jira/browse/SOLR-8707
             Project: Solr
          Issue Type: Improvement
          Components: update
            Reporter: Michael Sun


In current implementation, all Solr nodes start commit for all cores in a collection almost at the same time. As result, it creates a load spike in cluster at regular interval, particular when collection is on HDFS. The main reason is that all cores are created almost at the same time for a collection and do commit in a fixed interval afterwards.

It's good to distribute the the commit load evenly to avoid load spike. It helps to improve performance and reliability in general.
