AWS RDS Aurora MySQL Cluster, Reader Replica shows no connections

Question

I added a reader replica to my RDS Aurora MySQL cluster. The instance is running with minor cpu usage but it does not show connections on the monitoring page. I have enabled detailed monitoring. Access groups are the same as the writer instance.

How to I ensure that traffic is going to my reader instance?

Answer 1

AWS RDS Aurora does not support splitting of read/write transactions, In order to forward read only queries to read replica endpoint and read/write queries to your master endpoint you need to add function or a proxy to your application to inspect the query then forward it to read replica or to the master, in other word the application logic should manage this process.
