File src/kudu/integration-tests/alter_table-test.cc:

PS1, Line 891: this seems odd that the
             :   // "latest observed" timestamp is one higher than the thing we 
wrote
> the latest observed timestamp is read from the clock just before the scanne
you mean from the write response, right?

Is that a bug or a feature? i.e I would sort of expect that the "latest 
observed" would be exactly my timestamp, because my write didn't observe the 
timestamp after it. For example, if the timestamp after it was used to UPSERT 
on top of my INSERT, then my INSERT didn't "observe" the UPSERT (it would have 
failed had it observed it)
