Class InstanceAdminGrpc.InstanceAdminStub (6.86.0)

public static final class InstanceAdminGrpc.InstanceAdminStub extends AbstractAsyncStub<InstanceAdminGrpc.InstanceAdminStub>

A stub to allow clients to do asynchronous rpc calls to service InstanceAdmin.

Cloud Spanner Instance Admin API The Cloud Spanner Instance Admin API can be used to create, delete, modify and list instances. Instances are dedicated Cloud Spanner serving and storage resources to be used by Cloud Spanner databases. Each instance has a "configuration", which dictates where the serving resources for the Cloud Spanner instance are located (e.g., US-central, Europe). Configurations are created by Google based on resource availability. Cloud Spanner billing is based on the instances that exist and their sizes. After an instance exists, there are no additional per-database or per-operation charges for use of the instance (though there may be additional network bandwidth charges). Instances offer isolation: problems with databases in one instance will not affect other instances. However, within an instance databases can affect each other. For example, if one database in an instance receives a lot of requests and consumes most of the instance resources, fewer resources are available for other databases in that instance, and their performance may suffer.

createInstance(CreateInstanceRequest request, StreamObserver<Operation> responseObserver)

public void createInstance(CreateInstanceRequest request, StreamObserver<Operation> responseObserver)

Creates an instance and begins preparing it to begin serving. The returned long-running operation can be used to track the progress of preparing the new instance. The instance name is assigned by the caller. If the named instance already exists, CreateInstance returns ALREADY_EXISTS. Immediately upon completion of this request:

  • The instance is readable via the API, with all requested attributes but no allocated resources. Its state is CREATING. Until completion of the returned operation:
  • Cancelling the operation renders the instance immediately unreadable via the API.
  • The instance can be deleted.
  • All other attempts to modify the instance are rejected. Upon completion of the returned operation:
  • Billing for all successfully-allocated resources begins (some types may have lower than the requested levels).
  • Databases can be created in the instance.
  • The instance's allocated resource levels are readable via the API.
  • The instance's state becomes READY. The returned long-running operation will have a name of the format <instance_name>/operations/<operation_id> and can be used to track creation of the instance. The metadata field type is CreateInstanceMetadata. The response field type is Instance, if successful.
