     --default-backup-schedule-type=DEFAULT_BACKUP_SCHEDULE_TYPE
        The default backup schedule type that is used in the instance.
        DEFAULT_BACKUP_SCHEDULE_TYPE must be one of:

         AUTOMATIC
            A default backup schedule is created automatically when a new
            database is created in an instance. You can edit or delete the
            default backup schedule once it's created. The default backup
            schedule creates a full backup every 24 hours. These full backups
            are retained for 7 days.
         DEFAULT_BACKUP_SCHEDULE_TYPE_UNSPECIFIED
            Not specified.
         NONE
            No default backup schedule is created automatically when a new
            database is created in an instance.

     --description=DESCRIPTION
        Description of the instance.

     --edition=EDITION
        Cloud Spanner edition. You can upgrade your Standard edition instance
        to the ENTERPRISE edition or ENTERPRISE_PLUS edition. You can also
        upgrade your Enterprise edition instance to the ENTERPRISE_PLUS
        edition. Self-service downgrade isn't available. To downgrade the
        edition of your instance, file a support ticket. For more information,
        see the Spanner editions overview
        (https://cloud.google.com/spanner/docs/editions-overview)

     --expire-behavior=EXPIRE_BEHAVIOR
        The expire behavior of a free trial instance. EXPIRE_BEHAVIOR must be
        one of:

         free-to-provisioned
            When the free trial instance expires, upgrade the instance to a
            provisioned instance.
         remove-after-grace-period
            When the free trial instance expires, disable the instance, and
            delete it after the grace period passes if it has not been upgraded
            to a provisioned instance.

     --instance-type=INSTANCE_TYPE
        Specifies the type for this instance. INSTANCE_TYPE must be one of:

         free-instance
            Free trial instances provide no guarantees for dedicated resources,
            both node_count and processing_units should be 0. They come with
            stricter usage limits and limited support.
         provisioned
            Provisioned instances have dedicated resources, standard usage
            limits, and support.

     At most one of these can be specified:

       --nodes=NODES
          Number of nodes for the instance.

       --processing-units=PROCESSING_UNITS
          Number of processing units for the instance.
