    see the picture above, when user choose to use without a checkpoint to 
avoid catch up data after a crash , and use kafka#setStartFromLatest to consume 
the latest data. if use without the skip api , we can see that it can  produce 
a broken data which may lead to the alert in monitor Scenario。if user want to 
skip the broken window, can hava a choice to skip serveral window after the 
first fire.
