Why it matters
This feature addresses the issue of hidden or unintended databases that were potentially created to save broken tables, which can cause confusion or management difficulties. By displaying a clear warning, users are informed about these special databases, improving database management transparency and helping prevent accidental usage or neglect of such databases.How to use it
The warning is automatically displayed when ClickHouse detects databases that were created under the condition of saving broken tables. There is no additional configuration needed; users simply need to observe the warning messages in the database list or logs.
