Can you give examples of coherence protocols in use?

Can you give examples of coherence protocols in use?

Sure! Coherence protocols are used in various fields. For instance, in distributed computing, protocols like Paxos and Raft ensure consistency across nodes.

How does the Paxos protocol work?

Paxos works by having a proposer suggest a value, acceptors vote on it, and a learner learns the chosen value once a majority agrees.

What are the advantages of using Raft over Paxos?

Raft is generally considered easier to understand and implement than Paxos. It provides a more straightforward approach to leader election and log replication.

Can you give me a real-world application of these protocols?

Absolutely! Both Paxos and Raft are used in systems like Google Chubby and etcd, which manage distributed configurations and service discovery.
