Parameters
Name	Description
`data`	`array` Optional. Data for populating the Message object.
`↳ name`	`string` Output only. The name of the instance resource with the format: * projects/{project}/locations/{region}/clusters/{cluster_id}/instances/{instance_id} where the cluster and instance ID segments should satisfy the regex expression `[a-z]([a-z0-9-]{0,61}[a-z0-9])?`, e.g. 1-63 characters of lowercase letters, numbers, and dashes, starting with a letter, and ending with a letter or number. For more details see https://google.aip.dev/122. The prefix of the instance resource name is the name of the parent resource: * projects/{project}/locations/{region}/clusters/{cluster_id}
`↳ display_name`	`string` User-settable and human-readable display name for the Instance.
`↳ uid`	`string` Output only. The system-generated UID of the resource. The UID is assigned when the resource is created, and it is retained until it is deleted.
`↳ create_time`	`Google\Protobuf\Timestamp` Output only. Create time stamp
`↳ update_time`	`Google\Protobuf\Timestamp` Output only. Update time stamp
`↳ delete_time`	`Google\Protobuf\Timestamp` Output only. Delete time stamp
`↳ labels`	`array\|Google\Protobuf\Internal\MapField` Labels as key value pairs
`↳ state`	`int` Output only. The current serving state of the instance.
`↳ instance_type`	`int` Required. The type of the instance. Specified at creation time.
`↳ machine_config`	`Google\Cloud\AlloyDb\V1alpha\Instance\MachineConfig` Configurations for the machines that host the underlying database engine.
`↳ availability_type`	`int` Availability type of an Instance. If empty, defaults to REGIONAL for primary instances. For read pools, availability_type is always UNSPECIFIED. Instances in the read pools are evenly distributed across available zones within the region (i.e. read pools with more than one node will have a node in at least two zones).
`↳ gce_zone`	`string` The Compute Engine zone that the instance should serve from, per https://cloud.google.com/compute/docs/regions-zones This can ONLY be specified for ZONAL instances. If present for a REGIONAL instance, an error will be thrown. If this is absent for a ZONAL instance, instance is created in a random zone with available capacity.
`↳ database_flags`	`array\|Google\Protobuf\Internal\MapField` Database flags. Set at instance level. * They are copied from primary instance on read instance creation. * Read instances can set new or override existing flags that are relevant for reads, e.g. for enabling columnar cache on a read instance. Flags set on read instance may or may not be present on primary. This is a list of "key": "value" pairs. "key": The name of the flag. These flags are passed at instance setup time, so include both server options and system variables for Postgres. Flags are specified with underscores, not hyphens. "value": The value of the flag. Booleans are set to on for true and off for false. This field must be omitted if the flag doesn't take a value.
`↳ writable_node`	`Google\Cloud\AlloyDb\V1alpha\Instance\Node` Output only. This is set for the read-write VM of the PRIMARY instance only.

`↳ reconciling`	`bool` Output only. Reconciling (https://google.aip.dev/128#reconciliation). Set to true if the current state of Instance does not match the user's intended state, and the service is actively updating the resource to reconcile them. This can happen due to user-triggered updates or system actions like failover or maintenance.
`↳ etag`	`string` For Resource freshness validation (https://google.aip.dev/154)
`↳ annotations`	`array\|Google\Protobuf\Internal\MapField` Annotations to allow client tools to store small amount of arbitrary data. This is distinct from labels. https://google.aip.dev/128
`↳ update_policy`	`Google\Cloud\AlloyDb\V1alpha\Instance\UpdatePolicy` Update policy that will be applied during instance update. This field is not persisted when you update the instance. To use a non-default update policy, you must specify explicitly specify the value in each update request.
