Hi, Spark users, Following images are copied from spark streaming UI. I observed for about 30 minutes, and see that the Processed records(438768, at the moment I copied the image) are always lagging behind Received records(480783) by about 40k records, Since the waiting batches is 1 and the received records are many more than processed records, I can't understand why the total delay or scheduling day is not obvious（5 secs) here.
Can someone help explain what clues from this UI? Thanks. bit1...@163.com
