ScaleOut and ScaleUp architectures have guided the design and development of scalable database engines in the recent past. Novel hardware developments are promoting highly disaggregated computing platforms which allow a “best of breed” approach. Within the presentation, we will first sketch the threads and opportunities of disaggregated server infrastructures and will then pinpoint different research directions. Specifically, the talk will touch upon virtual vector processing, which facilitates SIMD-style programming without detailed knowledge of the underlying hardware infrastructure.

Wolfgang Lehner is full professor and head of the Database Technology Group at TU Dresden, Germany. His research focuses on database system architectures specifically looking at crosscutting aspects from data engineering algorithms and data structures down to hardware-related aspects mostly in main-memory centric settings. He is heading a Research Training Group on large-scale adaptive system software design and running a DFG-funded Reinhardt-Koselleck project on “Serverless Data Management Primitives for Software-defined Composable Systems”. Wolfgang Lehner serves the international database research community in many PCs, is the Managing Editor of “Proceedings of the VLDB Endowment” (PVLDB), and serves on the grants committee of collaborative research centers within the German Research Foundation (DFG). He is an appointed member of the Academy of Europe.
