In general you want to have memcached implemented for stuff like this. Have most used stuff closer/faster with memcached. I don't understand why they are running the whole nosql db on those monster machines - it just defeats the purpose. And sharding architecture that they are mentioning is quite error prone. I would go with read/write seperate channels for things of their nature - it appears they don't have that either.
