This topic introduces the short-lived connection optimization function provided by ApsaraDB RDS for MySQL in its dedicated proxy feature.


The dedicated proxy feature is enabled. For more information, see Dedicated proxy.

Background information

After a user terminates their connection with an RDS instance, the dedicated proxy of the RDS instance checks whether this connection is idle. If this connection is idle, the dedicated proxy releases its connection with the user, but retains its connection with the RDS instance in the connection pool for a specific retention period. If the user requests to connect to the RDS instance again within the retention period, the dedicated proxy retrieves its connection with the RDS instance from the connection pool to reduce overheads.
