Deleting a Read Replica
Scenarios
You can delete read replicas billed on a pay-per-use or serverless basis on the Basic Information page.
Constraints
- Deleted read replicas cannot be recovered. Exercise caution when performing this operation.
- You can only delete a read replica when the DB instance has two or more read replicas.
- If another operation is being performed on a DB instance, the read replicas of the instance cannot be manually deleted.
- For multi-AZ deployment, make sure that the primary node and remaining read replicas are located in different AZs after a read replica is deleted.
If a primary node and a read replica are deployed in AZ1 and the other read replica is deployed in AZ2, the read replica in AZ2 cannot be deleted.
- Before deleting the last serverless read replica, ensure that the function for adjusting the number of serverless read replicas has been disabled.
Procedure
- Log in to the management console.
- Click in the upper left corner and select a region and project.
- Click in the upper left corner of the page and choose Databases > GaussDB(for MySQL).
