No unfortunately it is not the case. The table record is written about 20 seconds before the stream record. I’ll crank up the time tomorrow and see what happens. On Tue, Nov 2, 2021 at 6:24 PM Matthias J. Sax wrote: > Hard to tell, but as it seems that you can reproduce the issue, it might > be

I did not study your code snippet, but yes, it sounds like a valid approach from your description. How can I be sure that the start of the window will coincide with the Punctuator's scheduled interval? For punctuations, there is always some jitter, because it's not possible to run a punctuat

Kafka streams event deduplication keeping last event in window

First I've tried to tackle the problem by using DSL API with [`.suppress(Suppressed.untilWindowCloses(...))`]( https://kafka.apache.org/21/documentation/streams/developer-guide/dsl-api.html) operator bu
