This is good info thanks. I have some cloud Infra experience so I am interesting in knowing how does they keep the data stored and remove the "query" servers when not in use.
Possibly some kind of EBS equivalent storage which is attached to the VM when it's booted up? I wonder that creates more failures at the cost of operational simplicity?
