Systems and devices for coordinating heterogeneous processes of a software application to comply with multiple address spaces or other computing system constraints are disclosed. In an example, operations for coordinating data processing among multiple processes of a software application include: executing a first process of the software application, as the first process operates with a first capability that is limited to an operational constraint of the computing system; initiating a second process of the software application, as the second process is initiated as a child of the first process, and as the second process operates with a second capability that exceeds the operational constraint of the computing system; communicating data from the first process of the software application to the second process; and receiving data from the second process of the software application, in response to the data being processed by the data analysis operations of the second process.
