Class InstanceAdminClient

public class InstanceAdminClient implements BackgroundResource

Service Description: 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.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 try (InstanceAdminClient instanceAdminClient = InstanceAdminClient.create()) {
   InstanceConfigName name = InstanceConfigName.of("[PROJECT]", "[INSTANCE_CONFIG]");
   InstanceConfig response = instanceAdminClient.getInstanceConfig(name);
 }

Note: close() needs to be called on the InstanceAdminClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of InstanceAdminSettings to create(). For example:

To customize credentials:


 InstanceAdminSettings instanceAdminSettings =
     InstanceAdminSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 InstanceAdminClient instanceAdminClient = InstanceAdminClient.create(instanceAdminSettings);

To customize the endpoint:


 InstanceAdminSettings instanceAdminSettings =
     InstanceAdminSettings.newBuilder().setEndpoint(myEndpoint).build();
 InstanceAdminClient instanceAdminClient = InstanceAdminClient.create(instanceAdminSettings);

Please refer to the GitHub repository's samples for more quickstart code snippets.

close()

public final void close()

createInstanceAsync(CreateInstanceRequest request)

public final OperationFuture<Instance,CreateInstanceMetadata> createInstanceAsync(CreateInstanceRequest request)

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.

Sample code:


 try (InstanceAdminClient instanceAdminClient = InstanceAdminClient.create()) {
   CreateInstanceRequest request =
       CreateInstanceRequest.newBuilder()
           .setParent(ProjectName.of("[PROJECT]").toString())
           .setInstanceId("instanceId902024336")
           .setInstance(Instance.newBuilder().build())
           .build();
   Instance response = instanceAdminClient.createInstanceAsync(request).get();
 }

updateInstanceAsync(Instance instance, FieldMask fieldMask)

public final OperationFuture<Instance,UpdateInstanceMetadata> updateInstanceAsync(Instance instance, FieldMask fieldMask)

Updates an instance, and begins allocating or releasing resources as requested. The returned long-running operation can be used to track the progress of updating the instance. If the named instance does not exist, returns NOT_FOUND.

Immediately upon completion of this request:

* For resource types for which a decrease in the instance's allocation has been requested, billing is based on the newly-requested level.

Until completion of the returned operation:

* Cancelling the operation sets its metadata's cancel_time, and begins restoring resources to their pre-request values. The operation is guaranteed to succeed at undoing all resource changes, after which point it terminates with a CANCELLED status. * All other attempts to modify the instance are rejected. * Reading the instance via the API continues to give the pre-request resource levels.

Upon completion of the returned operation:

* Billing begins for all successfully-allocated resources (some types may have lower than the requested levels). * All newly-reserved resources are available for serving the instance's tables. * The instance's new resource levels are readable via the API.

The returned long-running operation will have a name of the format <instance_name>/operations/<operation_id> and can be used to track the instance modification. The metadata field type is UpdateInstanceMetadata. The response field type is Instance, if successful.

Authorization requires spanner.instances.update permission on resource name.

Sample code:


 try (InstanceAdminClient instanceAdminClient = InstanceAdminClient.create()) {
   Instance instance = Instance.newBuilder().build();
   FieldMask fieldMask = FieldMask.newBuilder().build();
   Instance response = instanceAdminClient.updateInstanceAsync(instance, fieldMask).get();
 }

Parameters

Name	Description
instance	`Instance` Required. The instance to update, which must always include the instance name. Otherwise, only fields mentioned in field_mask need be included.
fieldMask	`FieldMask` Required. A mask specifying which fields in Instance should be updated. The field mask must always be specified; this prevents any future fields in Instance from being erased accidentally by clients that do not know about them.

Returns

Type	Description
OperationFuture<Instance,UpdateInstanceMetadata>

updateInstanceAsync(UpdateInstanceRequest request)

public final OperationFuture<Instance,UpdateInstanceMetadata> updateInstanceAsync(UpdateInstanceRequest request)
