How Many Databases Can Run on an RDS DB Instance?
The maximum number of databases that can run on an RDS DB instance depends on the DB engine settings.
If there are enough CPU, memory, and storage resources, there are no limitations to the number of databases running on a DB instance. However, the number of tables in the databases affects the backup speed. If there are more than 500,000 tables, the backup will fail.
- RDS for MySQL allows you to create numerous databases and tables. For details, see the official MySQL documentation.
- RDS for MariaDB allows you to create numerous databases and tables. However, due to factors such as the storage space and file system features, it is recommended that the total number of tables in an instance be no more than 2,000 to ensure high performance and stability.
- RDS for PostgreSQL allows you to create numerous databases and database accounts.
