But I’d like to add some extra high-availability for situations if

At least to achieve the ability of each node to serve calls among
those users who are registered directly on it.
What is the best architecture? Maybe something else, not MongoDB?
Hey Alexey,
MongoDB has worked fine for the federation use-cases I've deployed,
but only as long as you configure proper values for the connect timeout
setting, server selection timeout setting, and any other options which
may cause blocking when a Mongo cluster node is down [1].
PS: With the built-in MongoDB C library settings, the TCP connect
timeout is 10 seconds, which is abysmally large and will lead to
unacceptable PDD values if any of your POPs become isolated.
