   @kabike
   - the CI failure is not related.due to `Installing oraclejdk11 `, don't worry about this.
   - Yep,the description is a little misleading.IMO,What the "Single System Image" means is
that a client cannot read the stale data that it had ever read regardless of the server that
it connects to.   e.g:
   `set /key v1-->v2-->v3`
   A client's view of the /key cannot be like: `v1-->v3-->v2.`
   - For the implement, when the client reconnect to another server, that server will refuse
the connection when his current zxid is less than the client's lastZxid.
