trying the same scenario
Started my Streaming application 1:45 am
Window Time :7hrs
Watermark:1hr
Inserted some entries in source table at 1:48 am
write Stream:append Mode
Triiger Interval:10 Minutes

so my window time 12:00 am to 07:00 + watermark of 1hr
eventhough, when inserting an event after the watermark time,i.e 08:55 am,09:30am
I am not getting the older entries getting emitted
