The next version of MySQL will include a built-in memcached daemon. This daemon can quickly get and set key/value pairs from and to InnoDB tables while completely bypassing the parsing and planning overhead of SQL.
This could potentially be very awesome because we would then have a distributed key/value store that stores data in a way it can also be queried with complex SQL queries.
