Paxos
A distributed consensus algorithm proposed by Leslie Lamport in 1989 that solves the problem of reaching agreement on a value among multiple nodes in the presence of failures and message delays. It is noted for its difficulty of understanding and implementation, and serves as a classical theoretical foundation in distributed systems.
Core Facts
Timeline (last 90 days)
The Raft consensus algorithm is a distributed consistency algorithm used to manage replicated logs, proposed by Diego Ongaro and John Ousterhout in 2014, with the design goal of being easier to understand and implement than Paxos.
Geographic redundancy refers to deploying functionally equivalent computing and storage resources in multiple physically isolated locations, so that when any one site fails, operations can be taken over by other sites; distributed architecture further partitions data and computation across multiple nodes, maintaining overall availability through consensus protocols (such as Raft, Paxos) or eventual consistency models.
Consistency issues in cross-region data synchronization are typically addressed using the Paxos or Raft consensus protocols.
Raft is easier to understand in engineering implementation compared to Paxos and already has a mature open-source ecosystem such as etcd and TiKV.
In a Quorum cluster of 2f+1 nodes, an operation can be committed as long as f+1 nodes acknowledge it, and the system can tolerate f simultaneous node failures.
Paxos is known for being difficult to understand and implement.
Google's Chubby lock service is a production example built on Paxos.
Paxos is a consensus algorithm proposed by Leslie Lamport.
Raft is a consensus algorithm that is easier to understand than Paxos.
Classic consensus algorithms include Paxos and Raft, which are widely used in distributed databases.
