Exchange of Data Objects Between Task Routines Via Shared Memory Space

An apparatus includes a processor to: based on data dependencies specified in a job flow definition, identify first and second tasks of the corresponding job flow to be performed sequentially, wherein the first task outputs a data object used as an input to the second; store, within a task queue, at least one message conveying at least an identifier of the first task, and an indication that the data object is to be exchanged through a shared memory space; within a task container, in response to storage of the at least one message within the task queue, sequentially execute first and second task routines to sequentially perform the first and second tasks, respectively, and instantiate the shared memory space to be accessible to the first and second task routines during their executions; and upon completion of the job flow, transmit an indication of completion to another device via a network.
