Since May 2011 I am a PhD student in Database Architectures group at Centrum Wiskunde & Informatica (CWI). My research focuses on adaptive indexing. Specifically, I am working on holistic indexing, which is a novel approach to the automatic index selection problem. With holistic indexing we continuously monitor the workload and the CPU utilization. When under-utilized CPU cores are detected, holistic indexing spreads lightweight tuning actions across the index space.
