What is the number of concurrent queries supported by the medium database service?

The medium database service in Oracle Autonomous Database supports 20 concurrent queries. This means that when using this particular service tier, it is capable of handling up to 20 simultaneous SQL queries being executed at the same time. This limit is set to ensure optimal performance and resource utilization, enabling users to efficiently manage their workloads without overwhelming the system.

The choice of 20 concurrent queries aligns with the intended use of the medium service, which is designed for a balance of processing power and resource management, suitable for various applications requiring moderate query handling capabilities. Understanding this limit assists users in planning their database activities and avoiding bottlenecks caused by exceeding the permissible number of concurrent queries.
