When paxos meets erasure code
Shuai Mu, Kang Chen, Yongwei Wu, Weimin Zheng · 2014
Paxos-based state machine replication is a key technique to build highly reliable and available distributed services, such as lock servers, databases and other data storage systems. Paxos can tolerate any minority number of node crashes in an asynchronous network environment. Traditionally, Paxos is used to perform a full copy replication across all participants. However, full copy is expensive both in term of network and storage cost, especially in wide area with commodity hard drives.
