   * Server running mode

   * We use CAP theory to set the server mode, users can select their preferred mode in running time.
   * <p>
   * CP mode provides strong consistency, data persistence but network partition tolerance.
   * <p>
   * AP mode provides eventual consistency and network partition tolerance but data persistence.
   * <p>
   * Mixed mode provides CP for some data and AP for some other data.
   * <p>
   * Service level information and cluster level information are always operated via CP protocol, so
   * in AP mode they cannot be edited.
