An idiomatic C++ client library for the Cloud Data Fusion API, a fully-managed, cloud native, enterprise data integration service for quickly building and managing data pipelines.
While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/datafusion/quickstart/ directory, which should give you a taste of the Cloud Data Fusion API C++ client library API.
The main class in this library is datafusion_v1::DataFusionClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock datafusion_v1::DataFusionClient when testing your application.
