[K8SPSMDB-479] Allow MongoDB PODs to have non-voting members. #50

Closed spron-in closed 2 years ago

Community Note

Tell us about the feature Allow the MongoDB operator to define some nodes in mongo as a nonvoting members. This means they will have data but will never participate in voting and can never become primary. They will serve read-only traffic as a regular secondary but cannot become primary when voting happens. These nodes will be on edge locations to serve read traffic faster.

See reference links below

This is doable if run on VM but most likely not possible in operator.
