摘要

作者介绍了扭曲镜像，这是一种将任意写入语义与传统数据库指定块位置相结合的镜像系统。这种技术从根本上降低了小写入的成本;使其对OLTP等随机访问应用程序具有吸引力，同时保留了有效执行大型顺序访问的能力。在磁盘缓存和大型镜像集方面，扭曲镜像的可伸缩性也优于传统镜像。畸变镜的有效性在TP1基准上得到了验证。

Distorted mirrors

The authors introduce distorted mirrors, a mirroring system which combines write anywhere semantics with traditional database-specified block locations. This technique radically reduces the cost of small writes; making it attractive for random access applications such as OLTP, while retaining the ability to efficiently perform large sequential accesses. Distorted mirror also scale better than traditional mirrors in terms of both disk caching and large mirrored sets. The effectiveness of distorted mirrors is shown on the TP1 benchmark.<>
