Abstract
The present system improves the performance of a query in a database system when a plan for the query comprises sorting an input that is at least partially sorted such that a slow materialization sort can be applied. The invention applies the slow materialization sort by determining a sequence of subsets in accordance with the partially sorted input. As each of the subsets is determined, the subset is output for further processing. Advantageously, the invention reduces the waiting period for obtaining results from a sorting operation under certain circumstances.
