An idiomatic C++ client library for the Database Migration API, a service to Manage Cloud Database Migration Service resources on Google Cloud Platform.
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/datamigration/quickstart/ directory, which should give you a taste of the Database Migration API C++ client library API.
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.

idiomatic C++ client library for the [Database Migration API](https://cloud.google.com/database-migration), a service to Manage Cloud Database Migration Service resources on Google Cloud Platform.\n\nWhile this library is **GA** , please note Google Cloud C++ client libraries do **not** follow [Semantic Versioning](https://semver.org/).\n\n### Quickstart\n\nThe following shows the code that you'll run in the `google/cloud/datamigration/quickstart/` directory, which should give you a taste of the Database Migration API C++ client library API. \n\n #include \"google/cloud/datamigration/v1/data_migration_client.h\"\n #include \u003ciostream\u003e\n\n int main(int argc, char* argv[]) try {\n if (argc != 3) {\n std::cerr \u003c\u003c \"Usage: \" \u003c\u003c argv[0] \u003c\u003c \" project-id location-id\\n\";\n return 1;\n }\n\n namespace datamigration = ::google::cloud::datamigration_v1;\n auto client = datamigration::DataMigrationServiceClient(\n datamigration::MakeDataMigrationServiceConnection());\n\n auto const parent =\n std::string{\"projects/\"} + argv[1] + \"/locations/\" + argv[2];\n for (auto r : client.ListMigrationJobs(parent)) {\n if (!r) throw std::move(r).status();\n std::cout \u003c\u003c r-\u003eDebugString() \u003c\u003c \"\\n\";\n }\n\n return 0;\n } catch (google::cloud::Status const& status) {\n std::cerr \u003c\u003c \"google::cloud::Status thrown: \" \u003c\u003c status \u003c\u003c \"\\n\";\n return 1;\n }\n\n### Main classes\n\nThe main class in this library is [`datamigration_v1::DataMigrationServiceClient`](/cpp/docs/reference/datamigration/2.11.0/classgoogle_1_1cloud_1_1datamigration__v1_1_1DataMigrationServiceClient). All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock [`datamigration_v1::DataMigrationServiceClient`](/cpp/docs/reference/datamigration/2.11.0/classgoogle_1_1cloud_1_1datamigration__v1_1_1DataMigrationServiceClient) when testing your application.\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. Application developers can override the default policies.\n\n### More Information\n\n- [Error Handling](https://cloud.google.com/cpp/docs/reference/common/latest/common-error-handling.html) - describes how the library reports errors.\n- [How to Override the Default Endpoint](/cpp/docs/reference/datamigration/2.11.0/datamigration-override-endpoint) - describes how to override the default endpoint.\n- [How to Override the Authentication Credentials](/cpp/docs/reference/datamigration/2.11.0/datamigration-override-authentication) - describes how to change the authentication credentials used by the library.\n- [Environment Variables](/cpp/docs/reference/datamigration/2.11.0/datamigration-env) - describes environment variables that can configure the behavior of the library."]]
