Class InstanceAdminClient (6.62.0)

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:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 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().

Methods
Method	Description	Method Variants
ListInstanceConfigs	Lists the supported instance configurations for a given project.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listInstanceConfigs(ListInstanceConfigsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listInstanceConfigs(ProjectName parent) listInstanceConfigs(String parent) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listInstanceConfigsPagedCallable() listInstanceConfigsCallable()
GetInstanceConfig	Gets information about a particular instance configuration.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getInstanceConfig(GetInstanceConfigRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getInstanceConfig(InstanceConfigName name) getInstanceConfig(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getInstanceConfigCallable()
CreateInstanceConfig	Creates an instance config and begins preparing it to be used. The returned long-running operation can be used to track the progress of preparing the new instance config. The instance config name is assigned by the caller. If the named instance config already exists, `CreateInstanceConfig` returns `ALREADY_EXISTS`. Immediately after the request returns: * The instance config is readable via the API, with all requested attributes. The instance config's reconciling field is set to true. Its state is `CREATING`. While the operation is pending: * Cancelling the operation renders the instance config immediately unreadable via the API. * Except for deleting the creating resource, all other attempts to modify the instance config are rejected. Upon completion of the returned operation: * Instances can be created using the instance configuration. * The instance config's reconciling field becomes false. Its state becomes `READY`. The returned long-running operation will have a name of the format `<instance_config_name>/operations/<operation_id>` and can be used to track creation of the instance config. The metadata field type is CreateInstanceConfigMetadata. The response field type is InstanceConfig, if successful. Authorization requires `spanner.instanceConfigs.create` permission on the resource parent.

UpdateInstanceConfig	Updates an instance config. The returned long-running operation can be used to track the progress of updating the instance. If the named instance config does not exist, returns `NOT_FOUND`. Only user managed configurations can be updated. Immediately after the request returns: * The instance config's reconciling field is set to true. While the operation is pending: * Cancelling the operation sets its metadata's cancel_time. The operation is guaranteed to succeed at undoing all changes, after which point it terminates with a `CANCELLED` status. * All other attempts to modify the instance config are rejected. * Reading the instance config via the API continues to give the pre-request values. Upon completion of the returned operation: * Creating instances using the instance configuration uses the new values. * The instance config's new values are readable via the API. * The instance config's reconciling field becomes false. The returned long-running operation will have a name of the format `<instance_config_name>/operations/<operation_id>` and can be used to track the instance config modification. The metadata field type is UpdateInstanceConfigMetadata. The response field type is InstanceConfig, if successful. Authorization requires `spanner.instanceConfigs.update` permission on the resource name.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updateInstanceConfigAsync(UpdateInstanceConfigRequest request) Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service. updateInstanceConfigAsync(InstanceConfig instanceConfig, FieldMask updateMask) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updateInstanceConfigOperationCallable() updateInstanceConfigCallable()
DeleteInstanceConfig	Deletes the instance config. Deletion is only allowed when no instances are using the configuration. If any instances are using the config, returns `FAILED_PRECONDITION`. Only user managed configurations can be deleted. Authorization requires `spanner.instanceConfigs.delete` permission on the resource name.	Request object method variants only take one parameter, a request object, which must be constructed before the call. deleteInstanceConfig(DeleteInstanceConfigRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. deleteInstanceConfig(InstanceConfigName name) deleteInstanceConfig(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. deleteInstanceConfigCallable()
ListInstanceConfigOperations	Lists the user-managed instance config long-running operations in the given project. An instance config operation has a name of the form `projects/<project>/instanceConfigs/<instance_config>/operations/<operation>`. The long-running operation metadata field type `metadata.type_url` describes the type of the metadata. Operations returned include those that have completed/failed/canceled within the last 7 days, and pending operations. Operations returned are ordered by `operation.metadata.value.start_time` in descending order starting from the most recently started operation.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listInstanceConfigOperations(ListInstanceConfigOperationsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listInstanceConfigOperations(ProjectName parent) listInstanceConfigOperations(String parent) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listInstanceConfigOperationsPagedCallable() listInstanceConfigOperationsCallable()

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`.

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 the resource name.

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:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 InstanceAdminSettings instanceAdminSettings =
     InstanceAdminSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 InstanceAdminClient instanceAdminClient = InstanceAdminClient.create(instanceAdminSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 InstanceAdminSettings instanceAdminSettings =
     InstanceAdminSettings.newBuilder().setEndpoint(myEndpoint).build();
 InstanceAdminClient instanceAdminClient = InstanceAdminClient.create(instanceAdminSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 InstanceAdminSettings instanceAdminSettings =
     InstanceAdminSettings.newHttpJsonBuilder().build();
 InstanceAdminClient instanceAdminClient = InstanceAdminClient.create(instanceAdminSettings);

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 the resource name.

 }

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.

updateInstanceConfigAsync(InstanceConfig instanceConfig, FieldMask updateMask)

public final OperationFuture<InstanceConfig,UpdateInstanceConfigMetadata> updateInstanceConfigAsync(InstanceConfig instanceConfig, FieldMask updateMask)

Updates an instance config. The returned long-running operation can be used to track the progress of updating the instance. If the named instance config does not exist, returns NOT_FOUND.

Only user managed configurations can be updated.

Immediately after the request returns:

* The instance config's reconciling field is set to true.

While the operation is pending:

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

Upon completion of the returned operation:

* Creating instances using the instance configuration uses the new values. * The instance config's new values are readable via the API. * The instance config's reconciling field becomes false.

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

Authorization requires spanner.instanceConfigs.update permission on the resource name.
