No sorting in a sharded environment? Seriously? That's like having a car with no steering wheel.

Changing a shard key? Yeah, right. That's like trying to change your social security number - not happening.

Hmm, that makes sense too. I guess we need to review the sharding concept more thoroughly before the exam.
