Understanding Leader Election, Replication, and Split Brain in Distributed Systems

Leader election, replication, and split brain are core concepts in distributed systems, where multiple nodes coordinate to provide consistent data and service. Leader election ensures one node acts as the primary decision-maker, while replication copies data across nodes for fault tolerance. Split brain occurs when network failures cause nodes to act as separate leaders, leading to data conflicts and inconsistency.
