question: gets the parallelism for this contract instance . the parallelism denotes how many parallel instances of the user function will be spawned during the execution . if this value is -1 , then the system will decide the number of parallel instances by itself . concode_field_sep int parallelism concode_elem_sep OperatorInformation<OUT> operatorInfo concode_elem_sep CompilerHints compilerHints concode_elem_sep String name concode_elem_sep Configuration parameters concode_field_sep void setName concode_elem_sep String getName concode_elem_sep int getDegreeOfParallelism concode_elem_sep Configuration getParameters concode_elem_sep void setParameter concode_elem_sep void setParameter concode_elem_sep void setParameter concode_elem_sep Operator<T> createUnionCascade concode_elem_sep Operator<T> createUnionCascade concode_elem_sep Operator<T> createUnionCascade concode_elem_sep UserCodeWrapper<?> getUserCodeWrapper concode_elem_sep OperatorInformation<OUT> getOperatorInfo concode_elem_sep String toString concode_elem_sep void setDegreeOfParallelism concode_elem_sep void setParallelism concode_elem_sep CompilerHints getCompilerHints
