Transaction Scheduling in Multiclass Real-time Database Systems

Résumé du livre

Abstract: "In real-time database systems (RTDBS), the policy used for assigning priorities to transactions may lead to a biased treatment of different transaction classes. Such bias is not necessarily a reflection of differences in the tightness of the time constraints of these classes. Instead, it may be due to discrimination in the allocation of system resources. While bias due to differences in time constraint tightness is arguably reasonable, discrimination based on other class features (e.g., mean transaction size) may be unacceptable in many real-time applications. In this study, we focus on firm RTDBSs with multiclass workloads where classes are distinguished by their transaction sizes
