摘 要: | This paper presents a performance analysis of accessing tag data clustered in two different ways,namely event-wise clustering (generic tag)vs.attribute-wise clustering (sliced tag).The results show that especially “Prefetch-optimisation“ results in an additional performance gain of sliced tags over generic tags when only a subset of all the tag attributes is accessed.
