We were writing first to the master MySQL instance and then immediately putting the same data in memcached. When we read, we'd go to memcached first and then go to one of the read slaves. This way we would limit the effects of replication delay. Note that I don't necessarily like this scheme, but it's the one we used. Is there a replication delay issue with Keystore?
