Techniques for generating instructions to control database processing

An apparatus includes a task selector to receive an indication of a database task to be performed, wherein the database task includes first and second subtasks; a source selector to receive an indication of a source device to perform the first and second subtasks, and to retrieve from the source device an indication of a processing environment currently available within the source device that includes an identity and version level of a database routine of the specified source device; and an instruction generator to determine a set of languages able to be interpreted by the database routine based on the identity and version level, determine whether to perform the first and second subtasks in parallel based on the processing environment, select a language in which to generate instructions to perform the first subtask based on the determination, and generate and transmit the instructions to the source device.
