Leader Election, Replication, and Split Brain in Distributed Systems

What Are These Problems and Why Do They Matter? Distributed systems engineering deals with building reliable software that runs across multiple machines. When you have several servers working together, they need a way to coordinate their actions. Leader election, replication, and split brain are three core concepts that engineers must understand to keep a distributed system consistent and available. Leader election is the process by which a group of nodes picks one node
