Brad Glasbergen
I now work on the query optimizer team at Salesforce.

Previously, I completed a PhD at the University of Waterloo. I was advised by Khuzaima Daudjee.

I am interested in complex data systems, with a focus on leveraging machine learning techniques to improve performance and reliability.

Updates:
Dendrite received the Best Demonstration Award at SIGMOD 2021.

Our demonstration of the Sentinel system has received the Best Demonstration Award at SIGMOD 2020. Our research paper on Sentinel has been accepted into VLDB 2020.

I presented our geo-distributed predictive caching system, ChronoCache, at SIGMOD 2020.

Michael presented DynaMast, our system that eliminates distributed transactions by dynamically transferring the mastership of data items, at ICDE 2020.
Current Projects:
ChronoCache: A caching framework that uses online learning to predictively execute and cache database queries on edge servers closer to clients.

Dendrite: Capturing, understanding and powering automatic system adaption using performance metrics and logs from complex data systems.
