  The minimum sensible number of voting nodes to a replica set is three. MongoDB replication is synchronous. The Mongo shell is capable of attaching to a replica set and automatically failing over. By default, using the new MongoClient connection class, w=1 and j=1.

  mongodb mongoose node-mongodb-native
  Our MongoDB setup uses three replica set shards. Each webserver runs a mongos instance locally, and the client node.js processes connect through that using Mongoose (3.6.20) and node-mongodb-native. So node-mongodb-native just connects to mongos on localhost.When a replica set primary goes down hard (we can simulate this by doing ‘ifdown eth0’ on the primary) mongos properly detects this, and also detects that a new primary has been elected. So far, so good. But node-mongodb-native’s connections
