Primary/Secondary server Internals with OpLog

[anupkumarsharma]

Hey, This is more of a question than an issue.
I was looking into another connector Debezium and found a special case where they search for a primary server in the replication set. This solution doesn't handle this case. So, how does it affect when we have multiple replication sets and there is primary server failure?

Please correct me if I am wrong, but when the primary server handles an operation, it generates an oplog. This log then gets synced to other secondary servers. In our case since we maintain offset, even let say we lost connection to the primary. In this case, if we now switch to secondary server oplog, all the process will do is wait for the offset, until the secondary server's oplog get synced.
