> The 《CONSENSUS: BRIDGING THEORY AND PRACTICE》 has explain the JOINT consensus, which is implemented by ratis. But it didn't say how to configure the initial conf for new peers. I didn't find demonstration in ratis either.
>  
> Initial conf for new peers is easy to make mistakes and cause split brain or cluster unavailable as I will explain. I think we can add an example to illustrate how to initiate new peers when performing membership change.
