            --instance=my-instance-id --dual-region --etag=ETAG

POSITIONAL ARGUMENTS

      ◆ provide the argument database on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       DATABASE
          ID of the database or fully qualified identifier for the database.

          To set the database attribute:
          ▸ provide the argument database on the command line.

          This positional argument must be specified if any of the other
          arguments in this group are specified.

       --instance=INSTANCE
          The Cloud Spanner instance for the database.

          To set the instance attribute:

            specified name;
          ▸ provide the argument --instance on the command line;
          ▸ set the property spanner/instance.

       Command-line flag for dual-region quorum change:

       Command-line flags for single-region quorum change:

         --serving-location=SERVING_LOCATION
            The cloud Spanner location.

            This flag argument must be specified if any of the other arguments
            in this group are specified.

         --single-region
            Switch to single-region quorum type.

            This flag argument must be specified if any of the other arguments

        Used for optimistic concurrency control.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,

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 databases change-quorum

        $ gcloud beta spanner databases change-quorum
