Abstract

The author mainly concentrates on transactional distributed systems. Most previous research on replication in such environments has concentrated in employing replication to achieve high availability. The position is that high availability along is not enough. First, it is important to consider the cost of providing high availability through replication. Second, one must exploit the potential of replication as a means of improving performance. Then performance issues (in addition to availability) in which one is mostly interested are: transaction latency, bottlenecks and throughput, and scalability (in particular as it affects the former issues). The author briefly outlines his related research efforts which can be classified in the following areas: replication-control protocols, recovery strategies, and studying availability in large-scale distributed systems.<>

高可用性是不够的(分布式系统)
作者主要研究事务性分布式系统。以前关于这种环境中的复制的大多数研究都集中在使用复制来实现高可用性上。我们的立场是,只有高可用性是不够的。首先,重要的是要考虑通过复制提供高可用性的成本。其次,必须利用复制的潜力作为提高性能的一种手段。然后,人们最感兴趣的性能问题(除了可用性之外)是:事务延迟、瓶颈和吞吐量以及可伸缩性(特别是当它影响到前一个问题时)。作者简要概述了他的相关研究工作,可分为以下几个方面:复制控制协议、恢复策略和研究大规模分布式系统中的可用性。
