PacificA: Replication in Log-Based Distributed Storage Systems

Large-scale distributed storage systems have gained popularity for storing and processing ever increasing amount of data. Replication mechanisms are often key to achieving high availability and high throughput in such systems. Research on fundamental problems such as consensus has laid out a solid foundation for replication protocols. Yet, both the architectural design and engineering issues of practical replication mechanisms remain an art. This paper describes our experience in designing and i...
