Efficient large-scale processing of column based data encoded structures

摘要

The subject disclosure relates to efficient query processing over large scale data storage. An exemplary process includes retrieving a subset of columns implicated by a query as integer encoded and compressed sequences of values corresponding to different columns of data, defining query processing buckets that span over the subset of columns based on changes of compression type occurring in the integer encoded and compressed sequences of values of the subset of data and processing the query in memory on a bucket by bucket basis and processing the query based on type of current bucket when processing the integer encoded and compressed sequences of values. The column based organization of the data, and the application of a hybrid run length encoding and bit packing technique, enable a highly efficient and speedy query response in real-time.
