Abstract

A computer-implemented method includes inserting a bloom filter creation stage after an inner data source identification stage, wherein a join operation is to be performed to join an outer data source with the inner data source. The method inserts a bloom filter search stage after an outer data source identification stage, wherein each row of data from the outer data source is searched against a bloom filter for the inner data source during the bloom filter search stage. The method initializes a read on the inner data source. Subsequent to determining the bloom filter creation stage is complete, the method initializes a read on the outer data source. The method performs the join operation at a join stage.
