Jonathan Ellis commented on CASSANDRA-1034:
-------------------------------------------
Okay, we can skip the hashcode change if you're worried about boxing.
Yes, that's what I'm referring to for "kind." Seeing code like "if kind == 0"
means I have to go back to the kind method to see what a return value of 0
means.

> get_range_slices assumes that Tokens do not collide and converts a KeyRange
> to an AbstractBounds. For RandomPartitioner, this assumption isn't safe, and
> would lead to a very weird heisenberg.
> Converting AbstractBounds to use a DecoratedKey would solve this, because the
> byte[] key portion of the DecoratedKey can act as a tiebreaker.
> Alternatively, we could make DecoratedKey extend Token, and then use
> DecoratedKeys in places where collisions are unacceptable.
