Methods

CreateInstance(CreateInstanceRequest, ServerCallContext)

public virtual Task<Operation> CreateInstance(CreateInstanceRequest request, ServerCallContext context)

Creates an instance and begins preparing it to begin serving. The returned [long-running operation][google.longrunning.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][google.longrunning.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][google.longrunning.Operation.metadata] field type is [CreateInstanceMetadata][google.spanner.admin.instance.v1.CreateInstanceMetadata]. The [response][google.longrunning.Operation.response] field type is [Instance][google.spanner.admin.instance.v1.Instance], if successful.

Parameters
Name	Description
`request`	`CreateInstanceRequest` The request received from the client.
`context`	`ServerCallContext` The context of the server-side call handler being invoked.

Returns
Type	Description
`Task<Operation>`	The response to send back to the client (wrapped by a task).

CreateInstanceConfig(CreateInstanceConfigRequest, ServerCallContext)

public virtual Task<Operation> CreateInstanceConfig(CreateInstanceConfigRequest request, ServerCallContext context)

Creates an instance config and begins preparing it to be used. The returned [long-running operation][google.longrunning.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][google.spanner.admin.instance.v1.InstanceConfig.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][google.spanner.admin.instance.v1.InstanceConfig.reconciling] field becomes false. Its state becomes READY.

The returned [long-running operation][google.longrunning.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][google.longrunning.Operation.metadata] field type is [CreateInstanceConfigMetadata][google.spanner.admin.instance.v1.CreateInstanceConfigMetadata]. The [response][google.longrunning.Operation.response] field type is [InstanceConfig][google.spanner.admin.instance.v1.InstanceConfig], if successful.

Authorization requires spanner.instanceConfigs.create permission on the resource [parent][google.spanner.admin.instance.v1.CreateInstanceConfigRequest.parent].

DeleteInstance(DeleteInstanceRequest, ServerCallContext)

public virtual Task<Empty> DeleteInstance(DeleteInstanceRequest request, ServerCallContext context)

UpdateInstance(UpdateInstanceRequest, ServerCallContext)

public virtual Task<Operation> UpdateInstance(UpdateInstanceRequest request, ServerCallContext context)

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 [cancel_time][google.spanner.admin.instance.v1.UpdateInstanceMetadata.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][google.longrunning.Operation] will have a name of the format <instance_name>/operations/<operation_id> and can be used to track the instance modification. The [metadata][google.longrunning.Operation.metadata] field type is [UpdateInstanceMetadata][google.spanner.admin.instance.v1.UpdateInstanceMetadata]. The [response][google.longrunning.Operation.response] field type is [Instance][google.spanner.admin.instance.v1.Instance], if successful.

Authorization requires spanner.instances.update permission on the resource [name][google.spanner.admin.instance.v1.Instance.name].

Parameters
Name	Description
`request`	`UpdateInstanceRequest` The request received from the client.
`context`	`ServerCallContext` The context of the server-side call handler being invoked.

Returns
Type	Description
`Task<Operation>`	The response to send back to the client (wrapped by a task).

UpdateInstanceConfig(UpdateInstanceConfigRequest, ServerCallContext)

public virtual Task<Operation> UpdateInstanceConfig(UpdateInstanceConfigRequest request, ServerCallContext context)

Updates an instance config. The returned [long-running operation][google.longrunning.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][google.spanner.admin.instance.v1.InstanceConfig.reconciling] field is set to true.

While the operation is pending:

Cancelling the operation sets its metadata's [cancel_time][google.spanner.admin.instance.v1.UpdateInstanceConfigMetadata.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][google.spanner.admin.instance.v1.InstanceConfig.reconciling] field becomes false.

The returned [long-running operation][google.longrunning.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][google.longrunning.Operation.metadata] field type is [UpdateInstanceConfigMetadata][google.spanner.admin.instance.v1.UpdateInstanceConfigMetadata]. The [response][google.longrunning.Operation.response] field type is [InstanceConfig][google.spanner.admin.instance.v1.InstanceConfig], if successful.
