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}
