Abstract
In an example embodiment, a specialized execution process for a Disk Group-By operator with at least one distinct or ordered aggregation is provided. This specialized execution process involves writing all linked lists to disk (optionally this is performed only if the memory budget is coming close to being surpassed). Initially, a separate disk partition can be created per group, but once a partition becomes too large a new partition for the group is created. A partition is considered too large if it would not be able to be loaded into memory without surpassing the memory budget. As a result, every group can have a list of one or more disk partitions attached to it. The data belonging to each group is sorted using a sorted merge from disk.
