Classifying Suitability of Applications for the Hybrid Architecture

The hybrid architecture, HM-Hybrid can be an effective solution for a high volume stateful event processing that requires searches and updates to be consistent. The hybrid architecture provides high throughput by enabling batch update, but in the situation batch update is usually regarded as unsuitable because of its asynchronous characteristics. Therefore the hybrid architecture can be efficient for applications that must handle high volumes of searches and updates in a consistent manner. However, the range of its efficiency is still unclear, since its advantages depend on the application’s characteristics. We provide a methodology to estimates break-even points between advantages and disadvantages of the hybrid architecture. To compare them we introduce performance comparison models, and figure out the significant parameters to determine the throughputs of performance bottlenecks on the models. The range of efficiency of the hybrid architecture is clarified by this method, and it is shown to be applicable for a broad range of application patterns in our experiments.
