David Alves updated KUDU-430:
-----------------------------
Description:
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
