Abstract: A system and method are disclosed for processing input data in a multi-phase data processing pipeline. The system receives input data associated with an identifier and a plurality of attributes. Based on the identifier and attributes, the system determines one or more control requirements relevant to a first phase of the pipeline. For each control requirement, a corresponding function is selected and executed, producing control requirement results that are stored. The system modifies the input data in response to the control requirement results and according to the requirements of the first phase. The system stores the modified input data in a data store. A payload is generated containing the modified input data, the set of control requirement results, and the attributes. The system determines a subsequent phase based on the current phase and transmits the payload to that next phase for further processing.
