ClickHouse now generates a unique server UUID automatically on the first server start.
Why it matters
This feature ensures each ClickHouse server instance has a distinct identifier that can be used for tracking, replication, and cluster management, improving consistency and simplifying operations that rely on server uniqueness.How to use it
The UUID is generated automatically when the ClickHouse server starts for the first time. Users do not need to configure anything manually to enable this feature.
