Hi - any idea suggest what can a node with below configuration is capable of? In my opinion, this member cannot become primary, cannot vote and is also a delayed secondary, which is a combination of more than one use mentioned here - https://docs.mongodb.com/manual/administration/replica-set-member-configuration/
Can we use this node for performing any hot backups? I doubt, as it does not have latest data.
Can we still this node for performing any reads and writes? As its not hidden, this node can used to sync from by other nodes.
Any other clues?
