Class InstanceAdmin (2.34.0-rc)

Implements the APIs to administer Cloud Bigtable instances.

Thread-safety

Instances of this class created via copy-construction or copy-assignment share the underlying pool of connections. Access to these copies via multiple threads is guaranteed to work. Two threads operating concurrently on the same instance of this class is not guaranteed to work.

Cost

Creating a new object of type InstanceAdmin is comparable to creating a few objects of type std::string or a few objects of type std::shared_ptr<int>. The class represents a shallow handle to a remote object.

Error Handling

This class uses StatusOr<T> to report errors. When an operation fails to perform its work the returned StatusOr<T> contains the error details. If the ok() member function in the StatusOr<T> returns true then it contains the expected result. Operations that do not return a value simply return a google::cloud::Status indicating success or the details of the error Please consult the StatusOr documentation for more details.

namespace cbt = google::cloud::bigtable;
namespace btadmin = google::bigtable::admin::v2;
cbt::InstanceAdmin admin = ...;
google::cloud::StatusOr<btadmin::Instance> instance = admin.GetInstance(...);

if (!instance) {
  std::cerr << "Error fetching instance\n";
  return;
}

// Use `instance` as a smart pointer here, e.g.:
std::cout << "The full instance name is " << instance->name() << "\n";

In addition, the main page contains examples using StatusOr<T> to handle errors.

Retry, Backoff, and Idempotency Policies

The library automatically retries requests that fail with transient errors, and uses truncated exponential backoff to backoff between retries. The default policies are to continue retrying for up to 10 minutes. On each transient failure the backoff period is doubled, starting with an initial backoff of 100 milliseconds. The backoff period growth is truncated at 60 seconds. The default idempotency policy is to only retry idempotent operations. Note that most operations that change state are not idempotent. The application can override these policies when constructing objects of this class. The documentation for the constructors show examples of this in action.
