v.25.3Experimental Feature

Add support for dynamic cluster autodiscovery

Added support for dynamic cluster autodiscovery. This extends the existing node autodiscovery feature. ClickHouse can now automatically detect and register new clusters under a common ZooKeeper path using <multicluster_root_path>. #76001 (Anton Ivashkin).
Added support for dynamic cluster autodiscovery in ClickHouse, enabling automatic detection and registration of new clusters via a common ZooKeeper path.

Why it matters

This feature extends the existing node autodiscovery by allowing ClickHouse to automatically discover and register entire clusters dynamically. It solves the problem of manual cluster configuration and management, improving scalability and ease of cluster management in distributed environments.

How to use it

Users can enable dynamic cluster autodiscovery by specifying the <multicluster_root_path> in the configuration. ClickHouse will then use this ZooKeeper path to automatically detect and register new clusters without manual intervention.
