WebOct 12, 2024 · Based on the membership changes, the replication protocol also reconfigures the size of read and write quorums. To uniformly distribute the throughput that is assigned to a given physical partition, we employ two ideas: First, the cost of processing the write requests on the leader is higher than the cost of applying the updates on the follower. WebThe Raft consensus algorithm is a commonly used leader-based consensus protocol where a “leader” handles the task of data updates and replication. Strongly-consistent distributed databases have standardized onto this protocol. Leaderless consensus protocols are harder to implement but have higher availability than leader-based protocols.
