DESCRIPTION
    Update a Cloud Spanner instance.

EXAMPLES
    To update the display name of a Cloud Spanner instance, run:

        $ gcloud spanner instances update my-instance-id \
            --description=my-new-display-name

    To update the node count of a Cloud Spanner instance, run:

        $ gcloud spanner instances update my-instance-id --nodes=1

POSITIONAL ARGUMENTS
     INSTANCE
        Cloud Spanner instance ID.

FLAGS
     --async
        Return immediately, without waiting for the operation in progress to
        complete.

     --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
        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. You
        can downgrade your ENTERPRISE_PLUS edition instance to the ENTERPRISE
        or STANDARD edition. You can also downgrade your ENTERPRISE edition
        instance to the STANDARD edition. You must stop using the higher-tier
        edition features in order to downgrade. Otherwise, downgrade fails. For
        more information, see 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.

       Autoscaling

         --autoscaling-high-priority-cpu-target=AUTOSCALING_HIGH_PRIORITY_CPU_TARGET
            Specifies the target percentage of high-priority CPU the autoscaled
            instance can utilize.

         --autoscaling-storage-target=AUTOSCALING_STORAGE_TARGET
            Specifies the target percentage of storage the autoscaled instance
            can utilize.

         At most one of these can be specified:

           --asymmetric-autoscaling-option=[high_priority_cpu_target=HIGH_PRIORITY_CPU_TARGET],[location=LOCATION],[max_nodes=MAX_NODES],[max_processing_units=MAX_PROCESSING_UNITS],[min_nodes=MIN_NODES],[min_processing_units=MIN_PROCESSING_UNITS]
              Specify the asymmetric autoscaling option for the instance.

           --clear-asymmetric-autoscaling-option=LOCATION,[LOCATION,...]
              Specify a comma separated list of locations from which to remove
              asymmetric autoscaling options

         Autoscaling limits can be defined in either nodes or processing units.

         At most one of these can be specified:

           Autoscaling limits in nodes:

             --autoscaling-max-nodes=AUTOSCALING_MAX_NODES
                Maximum number of nodes for the autoscaled instance.

             --autoscaling-min-nodes=AUTOSCALING_MIN_NODES
                Minimum number of nodes for the autoscaled instance.

           Autoscaling limits in processing units:

             --autoscaling-max-processing-units=AUTOSCALING_MAX_PROCESSING_UNITS
                Maximum number of processing units for the autoscaled instance.

             --autoscaling-min-processing-units=AUTOSCALING_MIN_PROCESSING_UNITS
                Minimum number of processing units for the autoscaled instance.
