Why AWS aurora Read replica's slave status shows empty

Question

I have an Aurora replica, I know the primary and secondary instances are sharing an underlying Cluster volume.

When I run show slave status on the read replica, it shows nothing.

1. Why does it behave like this?

2. What kind of replication is aurora using?

Answer 1

1. Aurora does not use MySQL Binary Log File Position Based Replication method for its replication, which is why the SHOW SLAVE STATUS command does not show any information.

2. Aurora uses its own proprietary replication technology. See Replication with Amazon Aurora for the available documentation. To monitor Aurora replication status, you typically use the Amazon RDS Console to view dashboards of the relevant CloudWatch metrics. See Monitoring an Amazon Aurora DB Cluster for more information.
