   @simingweng  Im having trouble following what you are doing when there is a 
failed tuple. Not due to your code being confusing, i am just missing something 
and would like an explanation.  Are you replaying all tuples from the most 
recent failed offset?
   
   From what I have read in the code, i have come to believe this is your 
process, is this correct?
   1. Add offset to failure registry.
   2. Check if there is a failure.
   3. Seek to failure offset.
   4. Remove previous acks 
   5. Continue emitting..
   
   The code looks good. I plan on using this shortly and will hopefully have 
more feedback after i get into it. 
   
   Thanks!
