Server with Replicated Tables Can Start Without ZooKeeper Configuration

A server with replicated tables can start even if you haven’t configured ZooKeeper.
A ClickHouse server can now start with replicated tables without requiring ZooKeeper to be configured.

Why it matters

This feature addresses the need for improved server startup flexibility by allowing replicated tables to be used without immediate ZooKeeper configuration. It helps prevent startup failures and makes it easier to deploy and maintain ClickHouse instances in environments where ZooKeeper is not yet available or configured.

How to use it

Simply start the ClickHouse server with replicated tables defined, even if ZooKeeper configuration is missing or incomplete. The server will initialize and run without requiring ZooKeeper.
