Oh,it's designed for unaligned checkpoint.
Thanks,Zhanghao.

  Hi Enric,
  
 
  It basically means the prioritized buffers can bypass all non-prioritized 
buffers at the input gate and get processed first. You may refer to 
https://issues.apache.org/jira/browse/FLINK-19026&nbsp;for more details where 
it is firstly introduced.
  
 
   Best,
 Zhanghao Chen

   Hello,Community:
 &nbsp; I am puzzled by what the Priority means in Flink Buffer,it explains 
with example(as follows) in Buffer.java,but I still don't get what exactly is 
"it skipped buffers"??Could anyone give me a 
 
 intuitive explanation?
 &nbsp; Thanks.
