> 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
