FAQPage Schema
What are the main distributed consensus algorithms for replicated state machines?▼

This Skill summarizes Paxos, Multi-Paxos, Raft, and EPaxos to help system designers maintain consistency across failures in distributed systems.

How do I choose between Raft and Multi-Paxos for my distributed system?▼

Compare Raft and Multi-Paxos using this Skill's overview to select the appropriate consensus algorithm based on your specific system requirements for replicated state machines.

When should I use EPaxos instead of standard Paxos?▼

Use EPaxos over standard Paxos when your distributed system requires specific consistency guarantees that EPaxos handles more efficiently, as outlined in the algorithm comparison guidelines.

What are common pitfalls when implementing distributed consensus algorithms?▼

This Skill alerts system designers to common mistakes in implementing consensus algorithms, helping avoid errors when applying Paxos, Raft, or EPaxos to distributed systems.

How are consensus algorithms used in real-world systems like etcd and Spanner?▼

Consensus algorithms like Raft are used in real-world systems such as etcd, Consul, and Spanner to maintain consistency across distributed components, as demonstrated in this Skill's examples.

Do I need prior distributed systems knowledge to understand these consensus algorithm overviews?▼

Yes, understanding system design principles and familiarity with distributed systems are required to effectively use this Skill's concise overviews of Paxos, Raft, and EPaxos.
