Distributed Query Processing on the Cloud: the Optique Point of View
The optique european project aims at providing an end-to-end solution for scalable access to big data integration, where end users will formulate queries based on a familiar conceptualization of the underlying domain. From the users' queries the optique platform will automatically generate appropriate queries over the underlying integrated data, optimize and execute them on the cloud. In this paper, the authors present the distributed query processing engine of the optique platform. The efficient execution of complex queries posed by end users is an important and challenging task.
