Implementing Performance Competitive Logical Recovery

New hardware platforms, e.g. cloud, multi-core, etc., have led to a reconsideration of database system architecture. Our Deuteronomy project separates transactional functionality from data management functionality, enabling a flexible response to exploiting new platforms. This separation requires, however, that recovery is described logically. In this paper, we extend current recovery methods to work in this logical setting. While this is straightforward in principle, performance is an issue. We show how ARIES style recovery optimizations can work for logical recovery where page information is not captured on the log. In side-by-side performance experiments using a common log, we compare logical recovery with a state-of-the art ARIES style recovery implementation and show that logical redo performance can be competitive.Comment: VLDB201

Cricket: A Mapped, Persistent Object Store

This paper describes Cricket, a new database storage system that is intended to be used as a platform for design environments and persistent programming languages. Cricket uses the memory management primitives of the Mach operating system to provide the abstraction of a shared, transactional single-level store that can be directly accessed by user applications. In this paper, we present the design and motivation for Cricket. We also present some initial performance results which show that, for its intended applications, Cricket can provide better performance than a general-purpose database storage system

(To appear in Proc. of the 4th Intl. Workshop on Persistent Object Systems Design, Implementation and Use) 1. INTRODUCTION In recent years, there has been a great deal of research in extending database technology to meet the needs of emerging database applications such as text management and multi-media office systems (see [DBE87] for a good survey). Out of this research has come a v..
