Hi Team, I am using Flink File Source with window aggregator as process function, and stuck with a weird issues. File source doesn't seem emitting/progressing the watermarks, whereas if I put a delay (say 100ms) while extracting timestamp from event, it is working fine.
A bit same thing I found in comments here https://stackoverflow.com/questions/68736330/flink-watermark-not-advancing-at-all-stuck-at-9223372036854775808/68743019#68743019 Can someone help me here? Regards, Kirti Dhar
