Clusters can be removed without server restart upon config deletion

Clusters can be removed without restarting the server when they are deleted from the config files. #2777
Clusters can now be removed dynamically without requiring a server restart when they are deleted from the configuration files.

Why it matters

This feature allows administrators to apply changes to cluster configurations more smoothly by eliminating the need to restart the ClickHouse server after removing a cluster, thereby reducing downtime and improving operational efficiency.

How to use it

Simply delete the cluster definition from the configuration files, and the server will automatically recognize and remove the cluster without needing a restart.
