Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. If a primary server fails, a backup server can take over and continue to serve requests.

It is best practice to have an odd number of replica set members to maintain voting quorum. To make this process work more efficiently and ensure a smooth failover, it is important to have the same hardware configuration on all the nodes of the replica set. A replica set can currently have up to 50 nodes.

A data pipeline is a software which runs on hardware. The software is error-prone and hardware failures are inevitable. In certain scenarios exactly-once semantics is possible but the best you can do is at-least-once or at-most-once. A data pipeline can process data in a different order than they were received.
