Replica Set internal encryption MongoDB supports x.509 certificate authentication for use with a secure TLS/SSL connection Replica set members can use x.509 certificates to verify their membership to the replica set Enabling internal authentication also enables Role-Base Access Control (RBAC) This guide shows how to set up a 3 Node Replicaset in Mongodb with a standard Primary, Secondary and Arbiter (Non-data-holding cluster member). Otherwise, use the MongoDB installation tutorial and the Deploy a Replica Set tutorials. ensures that a replica set remains available if the primary or the For considerations when using an arbiter, see I'm not sure if this would be a regression from 3.6.x or a bug that was fixed in 3.6.x however given the following MongoDB cluster (single node replica set running in docker) the test will succeed in 3.5 and fail in 3.6. docker-compose.yml additional fault tolerance and high availability. Indexes are not visible in a MongoDB replica set. MongoDB starting from version 4 supports multi-document transactions only on a replica set. A three member replica set can have either three data-bearing members (Primary-Secondary-Secondary) (Recommended) or if circumstances (such as cost) prohibit adding a third data bearing member, two data-bearing members and an arbiter (Primary-Secondary-Arbiter). A Replica Set is a form of data replication, so that your data resides on more than one node for data durability.
