Abstract: The present disclosure relates to processing write requests across a plurality of data sources. According to one embodiment, an example method includes determining a navigable path of nodes accessed to satisfy a write request in a graph projection of an application programming interface (API). An API service generates a plurality of subqueries, each subqueries being associated with a node in the navigable path. While traversing the navigable path to execute the write request, the API service identifies one or more nodes in the navigable path sharing an association with a data repository associated with the current node and upon which execution of a write operation associated with the current node depends. The API service coalesces a set of subqueries associated with the current node and the identified one or more nodes into a single subquery and executes the single subquery.

Abstract: The present disclosure relates to processing read requests to retrieve data from a plurality of data sources. According to one embodiment, an example method includes determining a navigable path of nodes accessed to satisfy a read request based on a graph projection of an application programming interface (API). An API service generates a plurality of subqueries, each subqueries being associated with a node in the navigable path. While traversing the navigable path to satisfy the read request, the API service identifies data associated with lower level nodes that is cached at a data source associated with a current node, replaces subqueries directed to data stored at the current node and the identified data with a single subquery executed against the data source associated with the current node, and executes the single subquery at the current node. The API service returns data accessed during traversal of the navigable path.

Abstract: An apparatus and method for practicing calf-roping on live calves without the use of a roping horse. The novel calf-roping practice apparatus of the present invention comprises a rectangular chute which may be connected to the cattle chute of a stockyard or corral. The chute of the apparatus has a spring-loaded forward gate, which may be opened by pulling on a lever. The apparatus further comprises a take-up mechanism which is connected to the roping rope and which removes the slack in the rope after a calf has been roped. The apparatus is surmounted by a surface which simulates a horse's back, such that the user may secure his saddle thereon. The apparatus of the present invention may also include a spring-loaded neck mechanism which simulates a horse's neck and head.In use, the user ties his saddle on the apparatus and ties a string between one of the stirrups of the saddle and the lever which triggers the spring-loaded forward gate. The user then connects his rope to the take-up device of the apparatus.
