A High Performance Memory Database for Web Application Caches

Abstract—This paper presents the architecture and
characteristics of a memory database intended to be used as a
cache engine for web applications. Primary goals of this database
are speed and efficiency while running on SMP systems with
several CPU cores (four and more). A secondary goal is the
support for simple metadata structures associated with cached
data that can aid in efficient use of the cache. Due to these goals,
some data structures and algorithms normally associated with
this field of computing needed to be adapted to the new
environment.

How is it difference from other in-memory DB llike timesten / hsql? Faster for reading? What is the tradeoff??
