Hello,

currently the key vault has hardcoded majority read and write concern: https://github.com/mongodb/mongo-go-driver/blob/master/mongo/client.go#L40-L46

This does not let us run our applications with any other concern, since our applications utilize FLE. Even if the rest of the application uses read local and w=1, the key vault reads will hang indefinitely if a majority read is not currently available.

What is the rationale behind this? Would you be open to allowing a config entry point that would allow to change the read and write concern on the key vault to something else?

Thank you,

Elena Flat
