Development-time Best Practices
From Documentation
There are several settings below we recommend you to specify during development time that can improve your developer experience. They can show you more debugging information and disable various caches to get the latest change without restarting a server.
Separate zk.xml for Development
Put these development-time settings in a separate file, so that you can easily remove it for production in the future.
