Class DataTransferServiceClient (2.20.0)

This API allows users to manage their data transfers into BigQuery.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Returns
Type Description
StatusOr< google::cloud::bigquery::datatransfer::v1::DataSource >

the result of the RPC. The response message type (google.cloud.bigquery.datatransfer.v1.DataSource) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

GetDataSource(google::cloud::bigquery::datatransfer::v1::GetDataSourceRequest const &, Options)

Retrieves a supported data source and returns its settings.

Parameters
Name Description
request google::cloud::bigquery::datatransfer::v1::GetDataSourceRequest const &

Unary RPCs, such as the one wrapped by this function, receive a single request proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.datatransfer.v1.GetDataSourceRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.

opts Options

Type Description
StreamRange< google::cloud::bigquery::datatransfer::v1::DataSource >
