English abstract:
Complex Event Processing over Web service event
streams poses huge challenges with regard to efficient, scalable
execution as well as expressive models and languages that
account for the dynamics in long-running queries. We present
a distributed query platform that tackles these problems. Our
novel query model permits to specify inputs that provide data
for other inputs and need to be processed first. An XQuery
language extension lets users easily express such dependencies,
which are then continuously resolved with the required data
at runtime. Query specifications are abstracted from physical
deployment, allowing the platform to distribute the execution
and to elastically scale up and down. We evaluate several
aspects of our prototype in a Cloud computing environment.
