Serverless computing separates function execution from state management. Simple retry-
based fault tolerance might corrupt the shared state with duplicate updates. Existing …

State machine replication (SMR) is a core mechanism for building highly available and
consistent systems. In this paper, we propose Waverunner, a new approach to accelerate …

This paper presents a high-performance consensus protocol, Nezha, which can be
deployed by cloud tenants without any support from their cloud provider. Nezha bridges the …

Distributed protocols such as 2PC and Paxos lie at the core of many systems in the cloud,
but standard implementations do not scale. New scalable distributed protocols are …

State-machine replication protocols represent the foundation of many fault-tolerant services.
Unfortunately, their inherent complexity makes existing implementations notoriously difficult …

Distributed protocols such as 2PC and Paxos lie at the core of many systems in the cloud,
but standard implementations do not scale. New scalable distributed protocols are …

MySQL is the most popular transactional datastore deployed at Meta with a storage footprint
in the order of petabytes. Over the years, several components have undergone significant …

Distributed algorithms solving agreement problems like consensus or state machine
replication are essential components of modern fault-tolerant distributed services. They are …

State machine replication protocols such as Raft are widely used to build highly-available
strongly-consistent services, maintaining liveness even if a minority of servers crash. As …

PolarFS is a distributed file system developed by Alibaba with ultra-low latency and high
availability. It implements a variant of the Raft consensus protocol, called ParallelRaft …
