Constructor.

Parameters
Name	Description
`data`	`array` Optional. Data for populating the Message object.
`↳ name`	`string` Required. A unique identifier for the instance, which cannot be changed after the instance is created. Values are of the form `projects/<project>/instances/[a-z][-a-z0-9]*[a-z0-9]`. The final segment of the name must be between 2 and 64 characters in length.
`↳ config`	`string` Required. The name of the instance's configuration. Values are of the form `projects/<project>/instanceConfigs/<configuration>`. See also InstanceConfig and ListInstanceConfigs.
`↳ display_name`	`string` Required. The descriptive name for this instance as it appears in UIs. Must be unique per project and between 4 and 30 characters in length.
`↳ node_count`	`int` The number of nodes allocated to this instance. At most, one of either `node_count` or `processing_units` should be present in the message. Users can set the `node_count` field to specify the target number of nodes allocated to the instance. If autoscaling is enabled, `node_count` is treated as an `OUTPUT_ONLY` field and reflects the current number of nodes allocated to the instance. This might be zero in API responses for instances that are not yet in the `READY` state. If the instance has varying node count across replicas (achieved by setting asymmetric_autoscaling_options in autoscaling config), the node_count here is the maximum node count across all replicas. For more information, see Compute capacity, nodes, and processing units.
`↳ processing_units`	`int` The number of processing units allocated to this instance. At most, one of either `processing_units` or `node_count` should be present in the message. Users can set the `processing_units` field to specify the target number of processing units allocated to the instance. If autoscaling is enabled, `processing_units` is treated as an `OUTPUT_ONLY` field and reflects the current number of processing units allocated to the instance. This might be zero in API responses for instances that are not yet in the `READY` state. If the instance has varying processing units per replica (achieved by setting asymmetric_autoscaling_options in autoscaling config), the processing_units here is the maximum processing units across all replicas. For more information, see Compute capacity, nodes and processing units.
`↳ replica_compute_capacity`	`array<Google\Cloud\Spanner\Admin\Instance\V1\ReplicaComputeCapacity>` Output only. Lists the compute capacity per ReplicaSelection. A replica selection identifies a set of replicas with common properties. Replicas identified by a ReplicaSelection are scaled with the same compute capacity.
`↳ autoscaling_config`	`Google\Cloud\Spanner\Admin\Instance\V1\AutoscalingConfig` Optional. The autoscaling configuration. Autoscaling is enabled if this field is set. When autoscaling is enabled, node_count and processing_units are treated as OUTPUT_ONLY fields and reflect the current compute capacity allocated to the instance.
`↳ state`	`int` Output only. The current instance state. For CreateInstance, the state must be either omitted or set to `CREATING`. For UpdateInstance, the state must be either omitted or set to `READY`.
`↳ labels`	`array\|Google\Protobuf\Internal\MapField` 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`	`array` Deprecated. This field is not populated.
`↳ create_time`	`Google\Protobuf\Timestamp` Output only. The time at which the instance was created.
`↳ update_time`	`Google\Protobuf\Timestamp` Output only. The time at which the instance was most recently updated.
`↳ edition`	`int` Optional. The `Edition` of the current instance.

getLabels

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.
