Review Comment:
Is it possible that there is going to be more options inside the
RaftGroupOptions? Maybe it's not a good idea to use constructor here and you
already have factory methods. Maybe you can add some new method like
"RaftGroupOptions#optionsForTable(isVolatile)"? Does it make sense?

I think this `(in-memory)` can be omitted

Review Comment:
Sometimes you use static import for `RaftGroupOptions.defaults()`, and
sometimes you don't. Is there some logic behind it?

Review Comment:
Probably should be default or something. I don't see that we are ever going
to use different codecs (probably just the implementation of this one)
