Please visit the list of modified services if you have questions about university services.

Although the University of Waterloo is closed for in-person events until further notice, many virtual events and presentations of interest to computer scientists are taking place each week at the Cheriton School of Computer Science. Please check out what our students and faculty are doing.

PhD Seminar • Data Systems — Universal Behaviour Insights and Diagnosis for Data SystemsExport this event to calendar

Wednesday, November 27, 2019 — 12:15 PM EST

Bradley Glasbergen, PhD candidate
David R. Cheriton School of Computer Science

Data systems continue to grow in complexity in response to the need to manage vast quantities of data and support a variety of workloads. Small changes in workloads and system configuration can result in different system behaviour and performance characteristics. As a result, DBAs and system developers can spend many hours diagnosing and debugging performance problems in data systems and the applications that use them. 

I will present Sentinel, a system that constructs fine-grained models of system behaviour and enables diagnostic comparisons to understand how this behaviour differs for different workloads and system configurations. Sentinel’s insights are derived from built-in debug logs without necessitating that these logs are written to disk, thereby generalizing to all systems that use debug logging without incurring its overheads.
