Read replicas of an instance are used to enhance instance capabilities and reduce the read pressure on the primary node.

You can add read replicas to an existing yearly/monthly or pay-per-use instance.

Log in to the management console.
Click in the upper left corner and select a region and a project.
Click in the upper left corner of the page, choose Database > GaussDB(for MySQL).
On the Instances page, locate the instance that you want to create read replicas for and choose More > Create Read Replica in the Operation column.
On the Create Read Replica page, configure Failover Priority and Quantity.
- For a yearly/monthly instance, click Buy Now and select a payment mode.
- For a pay-per-use instance, click Next.
Check the read replica settings.
- If you need to modify the settings, click Previous.
- If you do not need to modify the settings, click Submit.
View the new read replica information in the Node List area of the Basic Information page. You can also promote a read replica to primary or delete a read replica.
