  • Method and system for storing tabular data in a memory-efficient manner
    Patent number: 9092470
    Abstract: Certain example embodiments relate to a method of storing data in a tabular data structure having columns and rows in a column-oriented storage system. At least one of the columns is divided into a plurality of segments. Each segment has an associated cell size that indicates the maximum size of the data items in the respective segment. When storing a data item into one of the segments, it is determined whether the size of the data item exceeds the cell size of the segment; and if the size of the data item exceeds the cell size of the segment, the cell size of the segment is adapted to accommodate the size of the data item. The adapting of the cell size of the segment to accommodate the size of the data item is performed independent of the cell sizes of the other of the plurality of segments.
