My congratulations! I was thought so too ... before have tested it. But
my surprise was when I've found the same data on every node. More over,
despite of redundancy, XC stop working if one node fails.

But it's no matter, because more important thing is that in any case for
every table You should choose either read or write scalability,
rewriting "CREATE TABLE" accordantly, while mysql cluster provides both
at the same time for all tables without any headache about distribution
schemas. i.e. all data are replicated and distributed at the same time.
The only essential difference, that prevent consider mysql cluster as
alternative for XC is that as I mentioned earlier, it is in-memory data
base and as so it is limited in size, while XC have no such limit.

Though be aware it's all about 1.0.0. I don't test all of these features
against 1.0.1 yet.
