Class v1.InstanceAdminClient (6.10.1)

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. v1

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of InstanceAdminClient.

Parameters
Name	Description
`opts`	`ClientOptions`
`gaxInstance`	`typeof gax \| typeof fallback` : loaded instance of `google-gax`. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new InstanceAdminClient({fallback: 'rest'}, gax); ```

Creates an instance and begins preparing it to begin serving. The returned 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:

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 will have a name of the format <instance_name>/operations/<operation_id> and can be used to track creation of the instance. The field type is . The field type is , if successful.

Returns

Type Description

AsyncIterable<protos.google.longrunning.IOperation>

{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing . The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results.

        {} | undefined
    ]>;

Updates an instance, and begins allocating or releasing resources as requested. The returned [long-running operation][google.longrunning.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 , 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 will have a name of the format <instance_name>/operations/<operation_id> and can be used to track the instance modification. The field type is . The field type is , if successful.

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

    ]>;

Updates an instance config. The returned 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 field is set to true.

* Cancelling the operation sets its metadata's . 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 field becomes false.

The returned will have a name of the format <instance_config_name>/operations/<operation_id> and can be used to track the instance config modification. The field type is . The field type is , if successful.
