Parallel processing of semantically grouped data in data warehouse environments

摘要

A system and method for parallel processing of semantically grouped data in data warehouse environments is disclosed. A datastore object having a number of records is generated in a data warehouse application. A hash value is added to each record. The hash value has an integer domain, and is uniformly distributed over the integer domain across the datastore object. A selection table is generated to create a number of tasks based on discrete ranges of the hash value. Then, a transformation routine is executed on each of the number of tasks in parallel to generate an infocube of data that corresponds to each range of the discrete ranges of the hash value.
