Abstract
A cell-specific dictionary is applied adaptively to adequate cells, where the cell-specific dictionary subsequently optimizes the handling of frequency-partitioned multi-dimensional data. This includes improved data partitioning with super cells or adjusting resulting cells by sub-dividing very large cells and merging multiple small cells, both of which avoid the highly skewed data distribution in cells and improve the query processing. In addition, more efficient encoding is taught within a cell in case the distinct values that actually appear in that cell are much smaller than the size of the column dictionary.
