Method, system, and article of manufacture for processing updates to insert operations

Abstract

A technique for processing input data is provided. Multiple input rows to beloaded into a first structure are received. Each input row of the multiple input rows is processed to classify each input row as one of an insert row and an update row, wherein input duplicates are stored in the first structure and index entries for the input duplicates are stored in a second structure. After the multiple input rows have been processed, the input duplicates are automatically re-applied to the first structure and the index entries stored in the second structure are processed.
