-------------------------------
Description:
I write a simple stream app followed official developer guide [Stream
DSL|[https://kafka.apache.org/22/documentation/streams/developer-guide/dsl-api.html#window-final-results]].
but I got more than one [Window Final
Results|https://kafka.apache.org/22/documentation/streams/developer-guide/dsl-api.html#id31]
from a session time window.
time ticker A -> (4,A) / 25s,
time ticker B -> (4, B) / 25s all send to the same topic
below is my stream app code
{code:java}
kstreams[0]

.groupBy((k, v) -> v, Grouped.with(Serdes.String(), Serdes.String()))

My source stream record rate is a same v record / 25s, gap of inactivity is
100s, 25<100. I shouldn't got so many window info print log. Session window
close and then reopened? my grace is 20 millisecond, it should not be ah.
was:
I write a simple stream app followed official developer guide [Stream
DSL|[https://kafka.apache.org/22/documentation/streams/developer-guide/dsl-api.html#window-final-results]].
yesterday that I got more than one [Window Final

My source stream record rate is a same v record / 25s, gap of inactivity is
100s, 25<100. I shouldn't got so many window info print log. Session window
close and then reopened? my grace is 20 millisecond, it should not be ah.

> I write a simple stream app followed official developer guide [Stream
