Towards workflow-driven database system workload modeling
Transaction relationships are usually ignored in current OLTP workload modeling and benchmark test system implementation. In this paper, two workflow driven models for real system workloads are proposed, one using Markov process, and the other Petri-net. Algorithms are also provided to keep the consistence between high-level semantic (workflow) and low level transaction mixing ratio in OLTP performance benchmarks. The experimental results have validated our approach.
