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. Webreplication scheme expands as the read activity increases, and it contracts as the write activity increases. When at each “border” processor (i.e. processor of the circumference …
