Data Management for Streaming Systems

Abstract

Many new computing applications are characterized by the arrival of asynchronous event data from the external world. These applications impose new requirements on the underlying system - requirements which are not addressed by the traditional timesharing model where user and application form a closed loop.

One area in which these differences are especially pronounced is that of data storage and retrieval. In this talk we examine two data handling systems for streaming data: TSAR, which provides an energy-efficient distributed data store to networks of tiny wireless sensors, and Hyperion, a distributed network monitor comprised of server-class machines, providing real-time recording and online querying of network data. Despite the vast differences in scale, these two systems must address similar application requirements and resource constraints. In this talk I will describe the theory and practice of these two systems, present results, and address the implications of new storage models for the future of operating systems research.
