Priority Mechanisms for OLTP and Transactional Web Applications
Transactional workloads are a hallmark of modern OLTP and Web applications, ranging from electronic commerce and banking to online shopping. Often, the database at the core of these applications is the performance bottleneck. Given the limited resources available to the database, transaction execution times can vary wildly as they compete and wait for critical resources. As the competitor is "Only a click away," valuable (high-priority) users must be ensured consistently good performance via QoS and transaction prioritization.
