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
cancelTime
, 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 aCANCELLED
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/<operationId>
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

Optional. The autoscaling configuration. Autoscaling is enabled if this field is set. When autoscaling is enabled, nodeCount and processingUnits are treated as OUTPUT_ONLY fields and reflect the current compute capacity allocated to the instance. |

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.).
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. |
