  /**
   * A type of consistency for ephemeral data.
   * <p>
   * This kind of consistency is not required to store data on disk or database, because the
   * ephemeral data always keeps a session with server and as long as the session still lives
   * the ephemeral data won't be lost.
   * <p>
   * What is required is that writing should always be successful even if network partition
   * happens. And when the network recovers, data of each partition is merged into one set,
   * so the cluster resumes to a consistent status.
