The foundational research lineage spanning performance diagnosis, workload modeling, robust design, approximate analytics, and predictable database behavior.
How can a data system make uncertainty, tradeoffs, and future behavior visible?
This program connects systems that diagnose and predict performance with systems that make explicit tradeoffs around latency, accuracy, and robustness. It provides the intellectual lineage for current work on systems that learn and optimize their own behavior.
Methods for diagnosing, bounding, and reducing performance variability under changing workloads.
Physical database designs that remain effective when workloads and estimates change.
Variance-aware and contention-aware scheduling for reducing tail latency and throughput collapse under high contention.
