SIGMOD2003: Adaptive Filters

Chris Olston, Jing Jiang, and Jennifer Widom, "Adaptive Filters for Continuous Queries Over Distributed Data Streams" SIGMOD 2003, pag 563-574

Research problem: Provide guaranteed bounds as answer to continuous queries at all times while filtering update streams at the source as much as possible.

Tools: continuous queries over network traffic.

load shedding, VLBD2006

Y.C. Tu, S. Liu, S. Prabhakar, B. Yao "Load Shedding in Stream Databases: A Control-Based Approach"

Describe how to handle the dynamic streams. It's a continuation of the Aurora paper.
AURORA has a feedback loop at the input, and it considers only the system's performance.
This paper introduces the notion of loop at the output values and it computes the errors between the output value and the desired value.
