What is the difference between Raft and Paxos?

Can you explain the main differences between Raft and Paxos?

Sure! Raft and Paxos are both consensus algorithms used in distributed systems, but they have different approaches. Raft is designed to be more understandable and easier to implement, while Paxos is more complex but has been around longer.

What are the key features of Raft?

Raft's key features include leader election, log replication, and safety guarantees. It ensures that all changes are agreed upon by a majority of nodes before being committed.

How does Paxos handle failures?

Paxos handles failures by allowing nodes to propose values and reach consensus even if some nodes fail. It requires a majority of nodes to agree on a value, which helps maintain consistency.

Which one is more widely used in practice?

Raft is often preferred in practice due to its simplicity and ease of understanding, while Paxos is more theoretical and used in some established systems.
