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. WebThe replication algorithm and consistency model explained below apply to AP data structures only. For CP subsystem and CP data structures, see the CP Subsystem section. …

There are two types of replication Algorithms. Read replication and Write replication. In Read replication multiple nodes can read at the same time but only one node can write. In Write replication multiple nodes can read and write at the same time. The write requests are handled by a sequencer.
