If you're using MySQL, you want MySQL Cluster, which distributes the
data over "data nodes" in a cluster and controls access through a "SQL
node".

Failing that, you want a dedicated connection-pooling utility between
the application and database layers which can route queries
appropriately; this is not logic that belongs in the application
layer, because the application should not need to know or care how
many databases are actually behind it.
