/**
 * 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.
