Systems, methods, and techniques for optimizing a plurality of data integration tasks within a data integration collection by identifying, as a sub-set of the plurality of data integration tasks, a plurality of point-to-point data integration tasks defining a data integration transformation plan to include: generating one or more publication data integration tasks comprising publishing from each respective data source of the plurality of point-to-point data integration tasks to generate a single publication topic; and generating one or more subscription data integration tasks causing each respective target of the plurality of point-to-point data integration tasks to subscribe to the single publication topic; and generating a set of optimization instructions configured to cause the at least one computer to implement the data integration transformation plan; and executing the set of optimization instructions to generate the one or more publication data integration tasks and the one or more subscription tasks.
