What is the Raft consensus algorithm?

What is the Raft consensus algorithm?

The Raft consensus algorithm is a distributed consensus algorithm designed to be understandable and efficient. It helps ensure that multiple servers agree on the same state, even in the presence of failures.

How does Raft handle leader election?

Raft uses a leader election process where servers can become candidates and request votes from other servers. If a candidate receives a majority of votes, it becomes the leader.

What are the main components of the Raft algorithm?

The main components of Raft include leader election, log replication, and safety mechanisms to ensure consistency across servers.

Can you explain log replication in Raft?

In Raft, the leader appends log entries and replicates them to follower servers. Followers acknowledge receipt, ensuring all servers maintain the same log.

What are the advantages of using Raft over Paxos?

Raft is often considered easier to understand and implement than Paxos, making it more accessible for developers while providing similar fault tolerance.
