[ https://issues.apache.org/jira/browse/FLINK-4683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15833214#comment-15833214 ]

-------------------------------------------------------------
Hi,[~fhueske] I picking up this issue of the reason, sliding-row window whether it is Stream or Batch logic (window division, trigger mechanism) should be consistent, by the same person to implement more convenient, so I want to pick up FLINK-4680 and FLINK-4683.:)
I agree with you about row-window (FLINK-4678, FLINK-4679, FLINK
-4680) We need a whole design, more importantly, we need to consider the design of the SQL implementation, and need to maintain a high degree of consistency with calcite .IMO, in fact OVER is the standard database window, perhaps in addition to the current flink There are three window types ("Tumbling Window", "Session Window", "Sliding Window"). We need a new window type. I want to call it "Relative Window".(the name We can discuss again).
What do you think ?
