Abstract
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
