             Summary: A new RESHARD command to increase no:of shards to have uniform sized shards
                 Key: SOLR-9322
                 URL: https://issues.apache.org/jira/browse/SOLR-9322
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Noble Paul


The SPLITSHARD is a rather blunt tool. It looks fine when you have very few no:of shards. If we have a very large no:of shards and we need to scale out by increasing the shard count by a smaller percentage (say 20% increase) it becomes rather useless.To achieve this we need to split the existing shards more smartly in such a way that the resulting shard set will have roughly similar no:of docs.
