Class BackupForGKEClient (2.14.0)

BackupForGKE allows Kubernetes administrators to configure, execute, and manage backup and restore operations for their GKE clusters.

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.

Type Description

future< StatusOr< google::cloud::gkebackup::v1::BackupPlan > >

The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a google.cloud.gkebackup.v1.BackupPlan proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

Type Description

StreamRange< google::cloud::gkebackup::v1::BackupPlan >

On a successful iteration the StatusOr<T> contains elements of type google.cloud.gkebackup.v1.RestorePlan, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.
