PaxosLease: Diskless Paxos for Leases
نویسندگان
چکیده
This paper describes PaxosLease, a distributed algorithm for lease negotiation. PaxosLease is based on Paxos, but does not require disk writes or clock synchrony. PaxosLease is used for master lease negotation in the open-source Keyspace replicated key-value store.

Empirical Study of Unstable
This thesis studies the effect of unstable leaders in Paxos protocol. Paxos algorithm is one of the most popular solutions for distributed consensus, and is often used for building replicated state machines. Safety is guaranteed by Paxos algorithm regardless of various machine and communication failures. However, the liveness is compromised when multiple Paxos leaders exist at the same time. Al...
متن کاملHow to Build a Highly Available System Using Consensus
Lamport showed that a replicated deterministic state machine is a general way to implement a highly available system, given a consensus algorithm that the replicas can use to agree on each input. His Paxos algorithm is the most fault-tolerant way to get consensus without real-time guarantees. Because general consensus is expensive, practical systems reserve it for emergencies and use leases (lo...
متن کاملHT-Ring Paxos: Theory of High Throughput State-Machine Replication for Clustered Data Centers
Implementations of state-machine replication (SMR) prevalently use the variants of Paxos. Some of the recent variants of Paxos like, Ring Paxos, Multi-Ring Paxos, S-Paxos and HT-Paxos achieve significantly high throughput. However, to meet the growing demand of high throughput, we are proposing HT-Ring Paxos, a variant of Paxos that is basically derived from the classical Paxos. Moreover, it al...

The precursor to this work (where diskless checkpointing was rst described) was presented at FTCS-24 27]. Abstract Diskless Checkpointing is a technique for checkpointing the state of a long-running computation on a distributed system without relying on stable storage. As such, it eliminates the performance bottleneck of traditional checkpointing on distributed systems. In this paper, we motiva...
متن کاملThe Performance of Paxos and Fast Paxos
Paxos and Fast Paxos are optimal consensus algorithms that are simple and elegant, while suitable for efficient implementation. In this paper, we compare the performance of both algorithms in failure-free and failure-prone runs using Treplica, a general replication toolkit that implements these algorithms in a modular and efficient manner. We have found that Paxos outperforms Fast Paxos for sma...
