An idiomatic C++ client library for the Cloud Dataplex API, an intelligent data fabric that helps you unify distributed data and automate data management and governance across that data to power analytics at scale.
While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/dataplex/quickstart/ directory, which should give you a taste of the Cloud Dataplex API C++ client library API.
This library offers multiple *Client classes, which are listed below. Each one of these classes exposes all the RPCs for a gRPC service as member functions of the class. This library groups multiple gRPC services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.
The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client classes when testing your application.
The library automatically retries requests that fail with transient errors, and uses exponential backoff to backoff between retries. Application developers can override the default policies.

Each one of these classes exposes all the RPCs for a gRPC `service` as member functions of the class. This library groups multiple gRPC services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.\n\nThe library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the `*Client` classes when testing your application.\n\n- [`dataplex_v1::ContentServiceClient`](/cpp/docs/reference/dataplex/2.11.0/classgoogle_1_1cloud_1_1dataplex__v1_1_1ContentServiceClient)\n- [`dataplex_v1::DataplexServiceClient`](/cpp/docs/reference/dataplex/2.11.0/classgoogle_1_1cloud_1_1dataplex__v1_1_1DataplexServiceClient)\n- [`dataplex_v1::MetadataServiceClient`](/cpp/docs/reference/dataplex/2.11.0/classgoogle_1_1cloud_1_1dataplex__v1_1_1MetadataServiceClient)\n\n### Retry, Backoff, and Idempotency Policies.\n\nThe library automatically retries requests that fail with transient errors, and uses [exponential backoff](https://en.wikipedia.org/wiki/Exponential_backoff) to backoff between retries.
