Managing Interfaces for Sub-Graphs

A method for configuring a dataflow graph template that includes one or more subgraph interfaces, the method including:

• generating in a development environment a dataflow graph template that includes a dataflow graph that includes one or more subgraph interfaces, with the one or more subgraph interfaces each having one or more flow junctions;
• generating in the development environment an implementation subgraph that conforms with a given subgraph interface;
• and
• configuring in the development environment the dataflow graph template by:
• dynamically linking the implementation subgraph in place of the given subgraph interface in the dataflow graph;
• and
• determining, for each flow junction of the given subgraph interface, a direction of metadata propagation, where the determined direction is one of an inward transfer of metadata from the flow junction on the given subgraph interface to a component of the dataflow graph or an outward transfer of the metadata from the flow junction on the given subgraph interface to the component of the dataflow graph.

One or more machine-readable hardware storage devices for configuring a dataflow graph template that includes one or more subgraph interfaces, the one or more machine-readable hardware storage devices storing instructions that are executable by one or more processing devices to perform operations including:

• generating in a development environment a dataflow graph template that includes a dataflow graph that includes one or more subgraph interfaces, with the one or more subgraph interfaces each having one or more flow junctions;
• generating in the development environment an implementation subgraph that conforms with a given subgraph interface;
• and
• configuring in the development environment the dataflow graph template by:
• dynamically linking the implementation subgraph in place of the given subgraph interface in the dataflow graph;
• and
• determining, for each flow junction of the given subgraph interface, a direction of metadata propagation, where the determined direction is one of an inward transfer of metadata from the flow junction on the given subgraph interface to a component of the dataflow graph or an outward transfer of the metadata from the flow junction on the given subgraph interface to the component of the dataflow graph.
