You can import data as follows:
# Import a JSON document into table `users` in database `my_db`
$ rethinkdb import -c HOST:PORT -f user_data.json --table my_db.users
# Import a CSV document
$ rethinkdb import -c HOST:PORT -f user_data.csv --format csv --table my_db.users
The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)
It does not balance, it leaves it to the kernel.
In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)
