  • Processing multi-way theta join queries involving arithmetic operators on MapReduce
    Patent number: 9870397
    Abstract: Methods, systems, and computer program products for processing multi-way theta join queries involving arithmetic operators on MapReduce are provided herein. A method includes converting (i) a multi-way theta join query into a multi-way interval join query, and (ii) one or more items of data associated with the multi-way theta join query to one or more items of interval data; executing the multi-way interval join query on the one or more items of interval data via MapReduce to generate an output, wherein the output comprises a set of multiple responses to the multi-way interval join query; and processing the output to generate a solution to the multi-way theta join query, wherein said processing comprises discarding each response from the set that does not satisfy the multi-way theta join query.
