Research
I invest most of my research energy into Avalanche, a project that I've set up with other folks of the Systems Group here at ETH. In Avalanche, we look at how modern hardware technologies can be used effectively to accelerate or otherwise improve database processing. More specifically, the Glacier query compiler that I build together with René Müller takes advantages of the potential offered by field-programmable gate arrays (FPGAs) and applies that in a data streaming context.
The transport mechanisms offered by modern network cards that support remote direct memory access (RDMA) significantly shift the priorities in distributed systems. Complex and sophisticated machinery designed only to avoid network traffic can now be replaced by schemes that can use the available bandwidth to their advantage. One such scheme is Data Cyclotron, a research effort that I work on jointly with the database group at CWI Amsterdam. Based on a simple ring-shaped topology, Data Cyclotron offers ad-hoc querying over data of arbitrary shape and arbitrary size.
Much of my past research work has revolved around the Pathfinder XQuery compiler. Pathfinder compiles expressions from the W3C XQuery language into a text book-style relational algebra, enabling traditional relational database back-ends to operate as high-performance XQuery processors. Pathfinder is distributed as MonetDB/XQuery, together with its primary database back-end MonetDB. In addition, Pathfinder provides support for SQL:1999-compliant databases, as well as for the commercial main-memory database kdb+.
