Reference documentation and code samples for the Google Cloud Spanner Instance Administration v1 API class UpdateInstanceRequest.
The request for
[UpdateInstance][google.spanner.admin.instance.v1.InstanceAdmin.UpdateInstance].
Required. A mask specifying which fields in
[Instance][google.spanner.admin.instance.v1.Instance] should be updated.
The field mask must always be specified; this prevents any future fields in
[Instance][google.spanner.admin.instance.v1.Instance] from being erased
accidentally by clients that do not know about them.
Required. The instance to update, which must always include the instance
name. Otherwise, only fields mentioned in
[field_mask][google.spanner.admin.instance.v1.UpdateInstanceRequest.field_mask]
need be included.
