Or you could use fixed point math: 600 in database means $6.00 Then aggregates and comparison operators would work, but you would have to decide upfront how much precision you might ever need

That sounds good, but with only 53 bits of integer precision in JSON (51 if you move the decimal point to account for cents), there's just not enough digits for finance these days. A similar problem exists if you use JSON numbers (aka doubles) for timestamps –- the numbers just aren't big enough to do it accurately.

I adjust the level of details and technical stuff pretty well according to who I am speaking to. But sometimes someone with very limited knowledge of something asks me a detailed question about X. What they ask is too difficult and complex to be described in a simple way. Either I have to overly simplify it which may insult them and will do no good or I have to go on and step by step give them digestible chunks of ex…

Looks like I'm one of the people you are referring to. Like anyone with a healthy dose of curiosity, I'm interested in anything that is, well, interesting. I'm excited to meet people with expertise in various areas and ask them questions. I don't expect to understand their answers in full but in most cases I can still grab part of them. Based on my partial understanding in the first answer I can ask a better question…

Try keeping it running while growing to millions of users in weeks. The simple data model lets us focus on elasticity and performance. There's a lot more to production quality software than the algorithms, but there are only a few NoSQL databases that get the algorithms right.

Sure, and I'm not trying to imply the RethinkDB guys are writing shoddy code or anything. For all I know the thing is bug-free with fantastic performance, perfect linear scaling with both number of cores and number of nodes in the cluster, and really does let you run your analytic workload on the same cluster you're taking transactions on (though I really doubt this last one – running analytics on your transactional…

Hey guys, Slava here. I've been up since yesterday, so I'm going to clock out (though some of the team members are still lurking here). I wanted to thank everyone for great feedback. We're working hard to improve Rethink over the next few months. FYI, you can always hop on IRC (#rethinkdb on freenode) or github tracker ( https://github.com/rethinkdb/rethinkdb/issues ) with questions and we'll help you out.
