Certain aspects of the present disclosure provide techniques for processing north-south queries in an application programming interface (API) generated for a plurality of associated services. The method generally includes receiving a request to invoke a function exposed by a first service in the API, wherein the function commits data to one or more data repositories. A data record is generated by the first service based on the received request based on a data object definition and a service definition for the first service. A message is generated including the generated data record and an indication that the message is to be consumed by a data lake processing system to commit data to a data lake. The message is published on a message bus for consumption by the data lake processing system.

Method and system for processing write queries in an application programming interface based on declarative schemas for individual services

Certain aspects of the present disclosure provide techniques for processing east-west queries in an application programming interface (API) generated for a plurality of associated services. The method generally includes receiving, at a request gateway from a requesting service, a request to invoke a function exposed by a first service through the API. References to entities defined in a declarative schema for one or more second services are identified based on identifiers included a record retrieved from a data repository for an entity returned by the function. A message is published on a message bus to the one or more second services to retrieve information related to the referenced entities. A response message including objects associated with the referenced entities is consumed. The function is executed based on the objects associated with the referenced entities, and the result generated by executing the function is returned to the requesting service.

Method and system for processing read queries in an application programming interface based on declarative schemas for individual services

Certain aspects of the present disclosure provide techniques for generating an application programming interface (API) for a plurality of associated services. The method generally includes retrieving a declarative schema for a service of a plurality of services in an application programming interface (API). A language object for the service is generated from a data object definition in the declarative schema associated with the service. Generally, the language object is configured to handle data events generated by the service. A service controller for the service is generated from a service definition in the declarative schema associated with the respective service. Generally, the service controller is fronted by a gateway for external sources to invoke one or more functions implemented by the service. An application programming interface (API) is exposed for the service independently of details of APIs for the associated services to one or more external services.
