Title
The Aurora and Medusa Projects
Abstract
This document summarizes the research conducted in two inte rrelated projects. The Aurora project being implemented at Brown and Brandeis under the direction of U ˘ gur Cetintemel, Mitch Cherniack, Michael Stonebraker and Stan Zdonik strives to build a single-site h igh performance stream processing engine. It has an innovative collection of operators, workflow orien tation, and strives to maximize quality of service for connecting applications. A further goal of Auro ra is to extend this engine to a distributed environment in which multiple machines closely co-operatein achieving high quality of service. In contrast, the Medusa project being investigated at M.I.T. under the direction of Hari Balakrish- nan and Michael Stonebraker is providing networking infras tructure for Aurora operations. In addition, Medusa is stressing distributed environments where the var ious machines belong to different organiza- tions. In this case, there can be no common goal, and much loos er coupling is needed. Medusa is work- ing on an innovative agoric infrastructure in which variousparticipants can co-operate in distributed streaming operations. Finally, some have questioned whether specialized stream p rocessing software is necessary. They speculate that conventional data base systems can adequate ly deal with the needs of stream-oriented applications. In order to answer this question one way or the other, both groups are working on a stream- oriented benchmark, called the Linear Road benchmark, which we intend to run on both specialized and conventional system infrastructure.
