"Providing QoS for dynamic web workloads is becoming increasingly
important in light of the competitive nature of e-commerce.

Natural QoS goals include (i) Prioritizing certain classes of
transactions; (ii) Guaranteeing mean response time targets for different
classes of transactions; (iii) Percentile guarantees, where at most x% of
response times are above y; (iv) Lowering overall variability in response
times across all classes.

Unfortunately, today's database servers, which are a common bottleneck in
serving dynamic requests, provide little QoS support. In this talk we will
investigate different ways of achieving the above QoS goals for
database-driven dynamic web workloads."
