Understanding Raft Consensus
A concise introduction to leader election, log replication, and why Raft makes distributed consensus easier to understand.
Understanding Raft Consensus
Raft is one of the easiest consensus algorithms to understand.
Motivation
Consensus allows multiple machines to agree on the same value.
go
type Node struct {
ID int
}Leader Election
Only one leader exists at a time.
Log Replication
The leader replicates logs to followers.
Conclusion
Raft prioritizes understandability without sacrificing correctness.
