Thanks Andrew. What i am looking for is how to balnce these read only connections between one read write, two read only nodes. all the writes will be hitting the read write node. when it comes to reads how the traffic gets diverted between three nodes. also we are planning to introduce load balancer to manage the read traffic. but in Ag the listener checks for synchronous read only replicas and diverts the read only traffic. the other replica is set for asnchronous commit. how the read traffic will get forwarded to this node?
