- 27. Groups !27 #jeeconf_atomix Raft RAFT The Raft protocol is aconsensus protocol developed in 2013. Consensus protocols are partition tolerant and provide strong consistency guarantees (linearizability, sequential consistency) that can be useful for coordination. However, strong consistency comes with a cost in terms of configuration and performance. Critically, Raft partition groups require explicitly defined membership. Each Raft group must identify the cluster members on which the group’s partitions will be replicated at startup. Without explicitly defined membership, Raft partitions may experience split brain when a network partition occurs while bootstrapping the cluster. The Raft partition group’s members must be PERSISTENT. This constraint exists because the semantics of persistent members accurately reflect the semantics of Raft cluster members: even after a Raft node crashes, the quorum size remains the same and the node still counts towards vote tallies. PB Even with sharding, Raft partition groups can be limited in their scalability. Writes to Raft partitions must be synchronously replicated to a majority of the cluster and must be flushed to disk prior to completion of a write operation. Primary-backup partition groups are a more efficient alternative to Raft partitions. Primary- backup replication works by electing a leader through which writes are replicated. The leader replicates to n backups based on the primitive configuration. Primary-backup partitions are Primary-Backup
