Quickstart
The following shows the code that you'll run in thegoogle/cloud/managedkafka/quickstart/directory, which should give you a taste of the Managed Service for Apache Kafka API C++ client library API.
This library offers multiple*Clientclasses, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple 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*Clientclasses when testing your application.
