摘要: Exploratory big data analytics requires the interaction delays to be kept at minimum. Although cubes help this goal by pre-calculating measures of interest, some aggregations are not decomposable and require runtime scans through cube which will cause response time exceed real-time limits. One such costly is calculation frequent patterns over partitions. The existing inefficient merge-and-count approach used for solving problem feasible in world data. In paper, an efficient proposed mining from accompanied a formal overview indecomposable aggregates. A new concept semi-decomposable aggregates introduced that sits between these two extremes. With case pattern problem, we show sometimes fact exploratory analysis can still realized them. FPCubes algorithm shows promising experimental results aggregating itemset on real-world multidimensional datasets.
