PPT-Raft: A Consensus Algorithm

for Replicated Logs Diego Ongaro and John Ousterhout Stanford University Replicated log gt replicated state machine All servers execute same commands in same order Consensus module ensures proper log replication. lastclcamacuk ABSTRACT The Paxos algorithm is famously dif64257cult to reason about and even more so to implement despite having been synonymous with dis tributed consensus for over a decade The recently proposed Raft protocol lays claim to being a n Paxos. --- 1.
