Thank you Fabian. I have one more question about timestamp: In the previous email, you asked how did I check the timestamp - I don't have an answer. Then I only checked the watermark, not the timestamp. I had the (wrong) assumption that watermarks advance along with timestamps. Today I played with that early trigger window, putting the output into a table, and found that the timestamp is set to the window's end-time, but the watermark seems not. (My window is [10:00-10:15), my incoming msgs both have time-stamp of 10:00, which trigger one early output with timestamp 10:14:59.999, but the watermark stays at 10:00)
Thus, my question: what is the easiest way to check the timestamp of a message? Thanks and regards, Averell -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
