What are Raft consistency models?

Can you explain what Raft consistency models are?

Raft is a consensus algorithm designed for managing a replicated log. It ensures that all nodes in a distributed system agree on the same sequence of operations, providing strong consistency.

How does Raft differ from Paxos?

While both Raft and Paxos are consensus algorithms, Raft is designed to be more understandable and easier to implement. Raft achieves consensus through a leader-follower model, whereas Paxos can be more complex due to its multiple roles.

What are the key components of the Raft algorithm?

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

Can you give an example of how Raft handles a network partition?

In a network partition, Raft ensures that only the majority of nodes can elect a leader and make progress. If a leader is isolated, it cannot make decisions until it regains contact with a majority.
