Daily Term: Leader Election

Leader Election

Leader Election is the process of selecting a single node as the leader or coordinator in a distributed system, often used in consensus algorithms like Raft. For example, in a distributed database, the leader might handle write operations, while followers replicate data. Leader election ensures a single point of coordination, improving consistency, but it requires mechanisms to handle leader failures and re-elect a new leader without disruption.
