Alexey Serbin commented on KUDU-420:
------------------------------------

One of the use-cases in this context is the following:
* On impala we gather the scan tokens on the frontend and set the "last 
propagated timestamp" based on what we got from previous writes.
* The scan tokens need to have that information embedded so that it is set when 
they are inflated.
* The {{propagated_timestamp}} field from those scan tokens should make its way 
into appropriate setting of the corresponding scanner objects, so the 
participating tablet servers would adjust their clocks accordingly upon 
receiving scan requests if the {{propagated_timestamp}} field is set.
