Have you tried HyperDB? It's what we use on WordPress.com to
distribute queries among slaves. It also detects write queries and
sends them to masters.


HyperDB has fallen behind WPDB (e.g. it lacks the new prepare and
update methods) so it needs some attention but nothing terribly
difficult. I'm sure the maintainers would be happy to see a patch from


Then again, if its capabilities were smartly integrated into WPDB it
could be even more beneficial.
