Continuously adaptive continuous queries over streams
We present a continuously adaptive, continuous query (CACQ) implementation based on the eddy query processing framework. We show that our design provides significant performance b...

An initial study of overheads of eddies
An eddy [2] is a highly adaptive query processing operator that continuously reoptimizes a query in response to changing runtime conditions. It does this by treating query process...

Using State Modules for Adaptive Query Processing
We present a query architecture in which join operators are decomposed into their constituent data structures (State Modules, or SteMs), and dataflow among these SteMs is managed ...

Lifting the Burden of History from Adaptive Query Processing
Adaptive query processing schemes attempt to reoptimize query plans during the course of query execution. A variety of techniques for adaptive query processing have been proposed,...
