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

rpc CreateInstance(CreateInstanceRequest) returns (Operation)

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.

Authorization Scopes

Requires one of the following OAuth scopes:

  • https://www.googleapis.com/auth/spanner.admin

CreateInstanceConfig

rpc CreateInstanceConfig(CreateInstanceConfigRequest) returns (Operation)

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.

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.

labels

map<string, string>

Cloud Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer's organizational needs and deployment strategies. Cloud Labels can be used to filter collections of resources. They can be used to control how resource metrics are aggregated. And they can be used as arguments to policy management rules (e.g. route, firewall, load balancing, etc.).

  • Label keys must be between 1 and 63 characters long and must conform to the following regular expression: [a-z][a-z0-9_-]{0,62}.
  • Label values must be between 0 and 63 characters long and must conform to the regular expression [a-z0-9_-]{0,63}.
  • No more than 64 labels can be associated with a given resource.

See https://goo.gl/xmQnxf for more information on and examples of labels.

If you plan to use labels in your own code, please note that additional characters may be allowed in the future. And so you are advised to use an internal label representation, such as JSON, which doesn't rely upon specific characters being disallowed. For example, representing labels as the string: name + "_" + value would prove problematic if we were to allow "_" in a future release.

endpoint_uris[]

string

Deprecated. This field is not populated.

Enums
INSTANCE_TYPE_UNSPECIFIED Not specified.
PROVISIONED Provisioned instances have dedicated resources, standard usage limits and support.
FREE_INSTANCE Free instances provide no guarantee for dedicated resources, [node_count, processing_units] should be 0. They come with stricter usage limits and limited support.

State

Indicates the current state of the instance.

Enums
STATE_UNSPECIFIED Not specified.
CREATING The instance is still being created. Resources may not be available yet, and operations such as database creation may not work.

etag

string

etag is used for optimistic concurrency control as a way to help prevent simultaneous updates of a instance config from overwriting each other. It is strongly suggested that systems make use of the etag in the read-modify-write cycle to perform instance config updates in order to avoid race conditions: An etag is returned in the response which contains instance configs, and systems are expected to put that etag in the request to update instance config to ensure that their change will be applied to the same version of the instance config. If no etag is provided in the call to update instance config, then the existing instance config is overwritten blindly.
