HADOOP OLAP ENGINE

摘要

In various example embodiments, systems and methods for building data cubes to be stored in a cube store are presented. In some embodiments, a metadata engine generates the cube metadata. In further embodiments, cube data is generated by a cube build engine based on the cube metadata and source data. The cube build engine performs a multi-stage MapReduce job on the source data to produce a multi-dimensional cube lattice having multiple cuboids. In further embodiments, the cube data is provided to the cube store.

1. A system comprising:
at least one processor of a machine; a metadata engine to generate cube metadata comprising dimension and measure information for a cube; and a cube build engine to generate cube data for the cube based on the cube metadata received from the metadata engine and source data, executing on the at least one processor of the machine, by performing a multi-stage MapReduce job on the source data to produce a multi-dimensional cube lattice having multiple cuboids, the cube build engine further to provide the cube data to a cube store.
