Multi-partition operation in combination operations

Abstract:

In an environment where multiple datasets are to be combined, systems and methods are disclosed for allocating a group of data entries from at least one dataset into multiple partitions. For a particular partition, the subgroup in the partition can be combined with data entries from the other dataset. In some cases, groups of data entries from each dataset are assigned to different partitions. For a particular partition, a subgroup is duplicated, some of the data entries of the subgroup are reassigned to other partitions, the subgroup is reformed to include data entries from other partitions, and the reformed subgroup is combined with the subgroup from the other dataset(s).
