Vectorizing Instance-Based Integration Processes

Abstract

Abstract. The inefficiency of integration processes-as an abstraction of workflow-based integration tasks-is often reasoned by low resource utilization and significant waiting times for external systems. Due to the increasing use of integration processes within IT infrastructures, the throughput optimization has high influence on the overall performance of such an infrastructure. In the area of computational engineering, low resource utilization is addressed with vectorization techniques. In this paper, we introduce the concept of vectorization in the context of integration processes in order to achieve a higher degree of parallelism. Here, transactional behavior and serialized execution must be ensured. In conclusion of our evaluation, the message throughput can be significantly increased.

Cost-based vectorization of instance-based integration processes

“…In this section, we give an overview of the core concepts of the process plan vectorization approach [6]. Therefore, we define the vectorization problem, explain the required modifications of the MTM, and illustrate the idea of the basic rewriting algorithm.…”

“…Further, we investigated the optimization of message transformation processes [8] and the cost-based optimization of instance-based integration processes [47]. Finally, the rule-based vectorization approach-presented in [6]-was the foundation of our cost-optimal solution to the vectorization problem.…”

“…This model is comparable to the iterator-based execution in DBMS [5]. In order to overcome the problem of low resource utilization, we introduced the vectorization of instance-based integration processes [6]. This approach describes the automatic and transparent rewriting of integration processes from the instance-based execution model into the pipes-and-filters execution model.…”
