Feature Description

max_user_connections specifies the maximum number of connections allowed for a single user. A value of 0 indicates no connection limit. When a user's concurrent connections exceed the value of max_user_connections, the server rejects new connection requests from that user.
When adjusting the max_user_connections parameter, you need to consider the following factors:
System resources: Set an appropriate value based on the actual server resources. When resources are sufficient, you can appropriately increase the value of max_user_connections to improve the system's concurrent processing capability. When resources are constrained, you need to decrease the value of max_user_connections to avoid resource exhaustion.
Application requirements: Set an appropriate value based on the actual application requirements. For high-concurrency applications, you may need to increase the value of max_user_connections to meet concurrency demands. For low-concurrency applications, you can decrease the value of max_user_connections to conserve system resources.
User management: Set an appropriate value based on the user's actual needs and permissions. For users with special permissions, you may need to increase the value of max_user_connections to meet their specific requirements. For regular users, you can decrease the value of max_user_connections to limit their resource usage.
