Abstract:
We propose a demonstration of Cayuga, a complex event
monitoring system for high speed data streams. Our demonstration
will show Cayuga applied to monitoring Web feeds;
the demo will illustrate the expressiveness of the Cayuga
query language, the scalability of its query processing engine
to high stream rates, and a visualization of the internals of
the query processing engine.

note: I just recently decided to revive this "blog", so this publication is already almost 2 years old.
