ApsaraDB RDS:What is availability detection?

Last Updated:Mar 28, 2026

Alibaba Cloud continuously monitors the health of your ApsaraDB RDS instance using one of two detection methods: short-lived connection or persistent connection. The default is persistent connection.

Choose a detection method

Application patternRecommended method
Frequently opens and closes connectionsShort-lived connection
Uses a connection poolPersistent connection (default)

If your application frequently opens and closes connections, use short-lived connection.

If your application uses a connection pool, keep the default persistent connection.

Note Changing the detection method does not affect workloads running on your RDS instance.
