Abstract:
A method, system, and computer program product for providing asynchronous resumption of a dataflow are provided. The method includes building an executable directed graph from a dataflow that includes multiple interconnected nodes, where at least one of the interconnected nodes is an asynchronous node. The method further includes creating an event flow that includes the asynchronous node and interconnections subsequent to the asynchronous node. The method also includes invoking execution of the executable directed graph, and creating a state object with an identifier associated with the event flow in response to reaching the asynchronous node. The method additionally includes continuing execution of the executable directed graph while avoiding the asynchronous node and the interconnections subsequent to the asynchronous node, and resuming execution of the event flow as identified via the state object upon receiving a response for the asynchronous node.
