The Architecture of PIER: an Internet-Scale Query Processor

by Ryan Huebsch, Brent Chun, Joseph M. Hellerstein, Boon Thau Loo, Petros Maniatis, Timothy Roscoe, Scott Shenker, Ion Stoica, Aydan R. Yumerefendi - In CIDR , 2005
"... This paper presents the architecture of PIER , an Internetscale query engine we have been building over the last three years. PIER is the first general-purpose relational query processor targeted at a peer-to-peer (p2p) architecture of thousands or millions of participating nodes on the Internet. ..."

. It supports massively distributed, database-style dataflows for snapshot and continuous queries. It is intended to serve as a building block for a diverse set of Internet-scale informationcentric applications, particularly those that tap into the standardized data readily available on networked machines

Pregelix: dataflow-based big graph analytics

by Yingyi Bu - In SoCC , 2013
"... model [2] for Big Graph analytics, where application pro-grammers need no knowledge of parallel or distributed sys-tems. Instead, they just need to “think like a vertex ” and write a few functions that encapsulate the logic for what one graph vertex does. The vertex-oriented programming model has be ..."

, instead of building a Pregel system from scratch, we explore an architectural alternative — express-ing Pregel’s semantics as database-style dataflows and exe-cuting them on a general-purpose data-parallel engine using classical parallel query evaluation techniques. We have used this approach to build

A Dataflow Approach to Agent-based Information Management

by Greg Barish , Daniel DiPasquo, Craig A. Knoblock, Steven Minton - IN PROCEEDINGS OF THE 2000 INTERNATIONAL CONFERENCE OF ON ARTIFICIAL INTELLIGENCE, LAS VEGAS, NV , 2000
"... Recent research has made it possible to build information agents that retrieve and integrate information from the World Wide Web. Although there now exist solutions for modeling Web sources, query planning, and information extraction, less attention has been given to the problem of optimizing agent ..."

execution. In this paper, we describe Theseus, an efficient plan execution system for information agents. Through its pipelined, dataflow-style architecture, Theseus offers a high degree of parallelism and asynchronous information routing during execution. Theseus differs from prior work in reactive

A graph model of data and workflow provenance

by Umut Acar, Peter Buneman, James Cheney, Jan Van Den Bussche, Natalia Kwasnikowska, Stijn Vansummeren - IN PROCEEDINGS OF THE 2ND USENIX WORKSHOP ON THE THEORY AND PRACTICE OF PROVENANCE (TAPP ’10 , 2010
"... Provenance has been studied extensively in both database and workflow management systems, so far with little convergence of definitions or models. Provenance in databases has generally been defined for relational or complex object data, by propagating fine-grained annotations or algebraic expression ..."

this gap by extending a previously-developed dataflow language which supports both database-style querying and workflow-style batch processing steps to produce a workflow-style provenance graph that can be explicitly queried. We define and describe the model through examples, present queries that extract
