I don't want to say too much, but the response time is not suitable to a real time application, queries will all take at least around a second to complete. But what users are querying explains why it takes a long time. Again, we're talking about a petabyte of data a day. Then in terms of cost it's around $0.5 per query maybe? The average is a very bad number because most queries will be something like $0.0001, but then some will be hundreds of dollars. But that's the only number I have off the top of my head.
