* @param string $ds Dataset: the name of the dataset. Just use “global” if you don’t need horizontal partitioning.
* @param int $part Partition: the vertical partition number (1, 2, 3, etc.). Use “0” if you don’t need vertical partitioning.
* @param string $dc Datacenter: where the database server is located. Airport codes are convenient. Use whatever.
* @param int $read Read order: lower number means use this for more reads. Zero means no reads (e.g. for masters).

* @param string $host Internet address: host:port of server on internet.
* @param string $lhost Local address: host:port of server for use when in same datacenter. Leave empty if no local address exists.
