<p>The subject disclosure relates to querying of column based data encoded structures enabling efficient query processing over large scale data storage, and more specifically, with respect to join operations. Initially, a compact structure is received that represents the data according to a column based organization, and various compression and data packing techniques, already enabling a highly efficient and fast query response in real-time. On top of already fast querying enabled by the compact column oriented structure, a scalable, fast algorithm is provided for query processing in memory, which constructs an auxiliary data structure, also column-oriented, for use in join operations, which further leverages characteristics of in-memory data processing and access, as well as the column-oriented characteristics of the compact data structure.</p> |
