Re: [janusgraph-foundationdb] initial fork options
Of course from my point of view, the easiest option is #2, taking my repo (rngcntr/janusgraph-foundationdb) as the base ;)
But to be honest, I don't think this is the cleanest way to go. I developed most of this alone and without review of others. Furthermore, I refactored much of the existing code. I can't speak for the other authors, but I think the situation might be similar for them.
So my suggestion would be to go for #1 or even better #4 as suggested by Misha.
