Abstract:
A method of analyzing a data parallel query includes receiving a user-specified data parallel query that includes a plurality of query operators. An operator type for each of the query operators is identified based on a type of parallel input data structure the operator operates on and a type of parallel output data structure the operator outputs. It is determined whether the query is a prohibited query based on the identified operator types.
