This module faciliates vertical sharding -- you can move tables to separate databases.
The main idea is to make Views build and execute a query which fetches IDs and then auxiliary queries fetching other fields from other databases. The fields involved in WHERE, ORDER, GROUP, HAVING should be in one database. The auxiliary queries on PHP 5.3 and MySQL will eventually use mysqli_poll to faciliate parallel processing.
