PolarDB:Is each physical database shard in PolarDB-X 1.0automatically deleted when the corresponding database is deleted? Are the ApsaraDB RDS for MySQL databases that belong to the deleted database affected?

No, some physical database shard in PolarDB-X is automatically deleted and the corresponding ApsaraDB RDS for MySQL databases are not affected. When you delete a PolarDB-X 1.0 database in the console, only the database that was created in PolarDB-X 1.0 is deleted. This does not affect the databases that were created in ApsaraDB RDS for MySQL.
