Availability detection is how ApsaraDB RDS monitors the health status of your RDS instance. RDS supports two detection methods: short-lived connection and persistent connection. By default, RDS uses persistent connections.
The right method depends on how your application connects to the database. Use the following table to choose based on your connection pattern.
Choose a detection method
| Connection pattern | Detection method | Why |
|---|---|---|
| Your application frequently opens and closes database connections | Short-lived connection | Matches how your app connects |
| Your application uses a connection pool | Persistent connection (default) | Consistent with pooled connection behavior |
Change the detection method
Changing the detection method does not affect workloads on your RDS instance.
