Abstract: A method, computer program, and computer system for updating a database system using a parallel application are disclosed. The parallel application includes a plurality of parallel operators. The method includes receiving records. A unique identifier is assigned to each record. A user defined rule condition is evaluated for each record. An action identifier is assigned to a subset of the records, based on the evaluation of the user defined rule condition. The records are transmitted to the database system with the unique identifiers and, for each of the subset of records, action identifiers.
