Re: The link to the documentation of JanusGraph 2.0 is broken
As Jason pointed out, JanusGraph 0.2.0 has not yet been released, but I have generated an unofficial build of the docs recently that you can preview here in the meantime:

Re: Embedded Cassandra version JG 0.2.0 ?
Sorry I should have asked more clearly. Can I have JG,Cassandra running lo multiple machines (connecting over localhost in each machine) and form a Cassandra cluster with all the Cassandra instances ?
