             Summary: Add Java system property for ZooKeeper config watch
                 Key: SOLR-16571
                 URL: https://issues.apache.org/jira/browse/SOLR-16571
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Nick Ginther


Solr creates a ZooKeeper watch per-core. On nodes with a lot of cores, this results in a lot of ZK watches, and thus increased resource consumption. ZK config watches aren't strictly necessary, so we should be able to disable them if we want to. To remedy this, we should add a Java system property to disable the ZK config watch per core. The default behavior should still be to create a ZK config watch per core.
