在分布式数据库应用程序中，数据经常被复制，以提高可用性和响应时间。传统的多副本算法为只读事务提供了快速响应时间和高可用性，同时牺牲了更新的这些目标。在本文中，我们提出了一个多副本算法，以及在检索和更新环境中利用特殊的应用语义。通过将事务细分为不同的类别，并利用交换性属性，我们展示了更便宜的技术，并表明它们保证正确性。我们的技术和传统技术之间的性能比较量化的节省的程度。
Data is often replicated in distributed database applications to improve availability and response time. Conventional multi-copy algorithms deliver fast response times and high availability for read-only transactions while sacrificing these goals for updates. In this paper, we propose a multi-copy algorithm that works well in both retrieval and update environments by exploiting special application semantics. By subdividing transactions into various categories, and utilizing a commutativity property, we demonstrate cheaper techniques and show that they guarantee correctness. A performance comparison between our techniques and conventional ones quantifies the extent of the savings.
