# Description 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. # Solution To remedy this, I've added a Java system property to disable the ZK config watch per core. The default behavior is still to create a ZK config watch per core. # Tests I've added a test confirming that the ZK watch is not created when the system property is set to true. # Checklist Please review the following and check all that apply: - [ ] I have reviewed the guidelines for [How to Contribute](https://wiki.apache.org/solr/HowToContribute) and my code conforms to the standards described there to the best of my ability. - [ ] I have created a Jira issue and added the issue ID to my pull request title. - [ ] I have given Solr maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
