/**
* A type of consistency for ephemeral data.
*
* 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.
*
* 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.
