DESCRIPTION
    (ALPHA) Update a Cloud Spanner instance.

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

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

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

        $ gcloud alpha 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.

     --description=DESCRIPTION
        Description of the instance.

     --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 (Preview)

         --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:

           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.

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. These variants are also available:

        $ gcloud spanner instances update

        $ gcloud beta spanner instances update
