Disclosed is a data processing system implemented method, a data processing system, and an article of manufacturing for use with the data processing system. The data processing system implemented method is used for directing the data processing system to join rows associated with a column of a source table with rows associated with a column of a target table. The data processing system includes a source node containing the source table and including a target node containing the target table. The method includes generating a reduced representation of selected rows associated with the column of the source table, and generating a representation of the column of the target table, filtering the generated reduced representation of selected rows associated with the column of the source table through the generated representation of the column of the target table, the filtered generated reduced representation of selected rows identifying source table rows that do not have to be joined with the target table, and joining, to the rows associated with the column of the target table, the rows associated with the column of the source table minus the filtered generated reduced representation of selected rows.
