Scheduled - We will be performing a ClickHouse Cloud shared catalog migration required to update table and database metadata.
During this maintenance window:

• DDL queries (CREATE/DROP/ALTER TABLE) will be temporarily unavailable.
• DML queries (INSERT/SELECT/UPDATE/DELETE) will continue to work normally.
• A short rolling restart of the service will occur.

This migration is required by ClickHouse Cloud to ensure continued stability and compatibility across Stellate environments.
