    Description

      When a new data coming and insert into Event Time Window, windowSize/slide subWindows are generated. and the data is copied to all of these subWindows. When the value of windowSize/slide is very big, redundancy is large, and this will slow the RocksDB's checkpoint. Event Window should redesigned, and candidate design is similar as Session window, only generating a pane(aligned with slide) when a new data come instead of generating a series of subWindows
