Date Fri, 04 Mar 2016 10:30:41 GMT

ASF GitHub Bot commented on FLINK-3554:

Github user wenlonglwl commented on the pull request:

    In our production environment, window is used to make a small batch, for some operator
that should be done in batch to improve the throughput, such as writing data to HBase, whether
the count reach or not, is not significant, but no losing data is. I think this is a common
user story.
