Method and system for decomposing a global application programming interface (API) graph into an application-specific API subgraph

A system, comprising:

• a processor;
• and
• a memory having instructions stored thereon which, when executed by the processor, performs an operation for generating application programming interface (API) code for an application, the operation comprising:
• receiving information indicating a set of queries invoked within an application;
• identifying a set of nodes in a graph projection of an API accessed by queries in the set of queries by traversing the graph projection of the API for each query in the set of queries;
• generating a subgraph projection of the API including the identified set of nodes and edges connecting the identified set of nodes discovered by traversing the graph projection of the API for each query in the set of queries;
• generating code implementing operations associated with the identified set of nodes from the generated subgraph projection of the API;
• and
• deploying the generated code for use with the application.

• generating a subgraph projection of the API including the identified set of nodes and edges connecting the identified set of nodes discovered by traversing the graph projection of the API for each query in the set of queries by:
• building a subgraph as a spanning tree from the identified set of nodes,
• traversing the graph projection of the API to add additional nodes to the subgraph according to a maximum traversal depth from each of the identified nodes, and
• truncating the subgraph to remove references to objects referenced by nodes in the subgraph but not included in the subgraph;
• generating code implementing operations associated with the identified set of nodes from the generated subgraph projection of the API;
• and
• deploying the generated code for use with the application.
