And here's my final answer :)
You can create the table in any MySQL Server and you can see all the content of it from
any MySQL Server. To see the tables you need to create the same database in all MySQL
Servers but the tables are "auto-discovered" if the database exists and you try to use the
tables.

The actual content of the tables are stored in the data nodes of the cluster and distribution
is transparent to the server.

Correct on last question and first question was answered above I hope.
