Dagstuhl-Seminar — Robust Query Processing in the Cloud

Following up on earlier Dagstuhl Seminars on robust performance of database query processing, this Dagstuhl Seminar aims to discuss and advance multiple topics in database query processing, with a new focus on cloud-computing environments. Query performance and in particular robust, predictable, reliable query performance (“good performance every time”) remains an open issue in research and in products. The problem is simple to describe, expensive to investigate and to alleviate, and well-known for decades: therefore, it must be a hard research problem that must be continuously investigated and reframed as technology develops (it is not a simple industrial development problem). A new dimension of complexity is added to this long-lasting problem with the ever-increasing popularity of cloud computing and the massive migration of database applications and services to this new environment.
