Let say there are 5 versions for a column A with timestamp = [0, 1, 3, 6,
I want to execute an efficient query that returns one version of the column
that has a timestamp that is equal to 5 or less. So in this case, it should
return the value of the column A with timestamp = 3.
Using the setTimeRange(5, Long.MAX_VALUE) with setMaxVersion = 1, my guess
is that it will return the version 6 not version 3. Correct me if I'm
