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.

- 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).

google.iam.v1.policy_pb2.Policy | Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource. **JSON Example** { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": ["user:eve@example.com"], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" ]="" }="" **yaml="" example**="" bindings:="" -="" members:="" -="" user:\="" mike@example.com="" -="" group:\="" admins@example.com="" -="" domain:google.com="" -="" serviceaccount:\="" my-project-id@appspot.gserviceaccount.com="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:\="" eve@example.com="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time="">< timestamp('2020-10-01t00:00:00.000z')="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the="" [iam="" developer's="" guide](\=""> |

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 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][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]
