Bloom filter utilization for join processing

A method comprising:

• inserting, by one or more processors, 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;
• responsive to determining a plurality of optimization conditions are satisfied, wherein the plurality optimization conditions at least specify that the join operation does not have any additive stages between the inner data source and a join stage, determining, by one or more processors, to insert a first bloom filter search stage after an outer data source identification stage;
• inserting, by one or more processors, the first bloom filter search stage after the outer data source identification stage, wherein each row of data from the outer data source is searched against a first bloom filter for the inner data source during the first bloom filter search stage;
• initializing, by one or more processors, a read on the inner data source, wherein a plurality of rows from the inner data source pass through to the join stage;
• responsive to determining the bloom filter creation stage is complete, initializing, by one or more processors, a read on the outer data source against the first bloom filter, wherein the plurality of rows from the inner data source pass through to the bloom filter creation stage;
• and
• performing, by one or more processors, the join operation of the inner data source and the outer data source at the join stage.
