Methods, systems, and devices for data processing are described. The method may include generating a federated application programming interface (API) from a plurality of data sources. One or more of the plurality of data sources may include an annotated data schema that defines one or more API endpoints for performing a distributed mutation of the plurality of data sources according to a supported distributed transaction protocol. The method may include receiving, via a single call to a single field of the federated API, a request at the federated API to perform a distributed mutation on the plurality of data sources. The method may include orchestrating, via a federation management service and the one or more API endpoints, a plurality of mutation calls to the plurality of data sources according to the distributed transaction protocol.
