It's no small feat to maintain compatibility with other product and reverse engineer changes as they happen. Good luck with that. How many people does AWS have people working on their version of elasticsearch? and on the client libraries in various languages? From previous discussions on HN, I was under the impression that the answer is very little if any. My bet is that AWS will keep the service as it is now and never makes patches or upgrades. That's how they operate services usually. And it's not that bad to be fair, the product is good enough as it is.
