It is recommended to keep the number of databases in a single instance below the maximum limit, which is related to the number of CPU cores of the instance. For detailed formulas on the maximum number of databases for each version, see Number of Databases.
Is there a limit on the number of tables for a single instance of TencentDB for SQL Server?
Theoretically, there is no limit on the number of tables for a single instance of TencentDB for SQL Server. However, if the number of tables exceeds 1 million, it may affect database performance. Please regulate the number of tables to ensure it does not exceed 1 million per instance.
