It says that is the "continuation" of C-JDBC. In other words, it's the
same project.
I just took a look at the c-jdbc design and it seems that they have to
execute writes one at a time (one insert statement at a time) -
because if
you start multiple write transaction at the same time then multiple
sites
could execute the writes in different orders. So it's not a good

solution except for read-mostly applications.
Sounds a bit limited; you would have thought it was fairly easy to
send multiple statements in a transaction as an atomic operation to
the cluster of databases.
