I have a mongod replication cluster as PSA architecture. I have configured the connection string in application which includes both primary and secondary servers ip and port, which helps to direct write and read queries to primary or secondary node.
Now when I stepdown the primary node, then my secondary node becomes primary node with the help of arbiter’s vote. At database side there is no issue like I can still connect to primary node whichever it is. But while application is connected to the primary and I do the switchover, application should be able to redirect its pointing to new primary node. But that is not the case. I need to stop the application services and then start again for the application to connect to new primary node.
But that is not the case for PSS cluster. In this case application is able to redirect its pointing to new primary node without any restart.
Why is it and what is the difference between two clusters? Is PSA cluster useless even in test/UAT environemt?
