> A number of small subtasks remain before we fully support snapshot 
> consistency.
> In particular, a few of the issues:
> - right now, after compactions, we can lose history for a given row, and then 
> a snapshot read in the past wouldn't produce correct results.
> - the C++ client doesn't handle timestamp propagation
> - we need to evaluate and make sure all of our APIs are in good shape in both 
> Java and C++ clients
> - need to add some security (hashes) around timestamp propagation to prevent 
> malicious clients from mucking with our machinery
> Scope Doc: 
> https://docs.google.com/document/d/1EaKlJyQdMBz6G-Xn5uktY-d_x0uRmjMCrDGP5rZ7AoI/edit#
