The question when to set a timestamp into BU when no immediate flush ? 
I think like in transactional case, where BU is not flushed immediately, the
timestamp is set during insertion of the BU into transactional log, same
could be in the case when BU is inserted into  cache. BTW, setting it in the
client will act exactly the same.

> The commit(BatchUpdate) and commit(list<BatchUpdate>) should return timestamp that BatchUpdate was committed with (in the case of commit(list<BatchUpdate> should return array of timestamps). 
> This should reduce number of round trips and improve performance in update operations.
