-------------------------------------------------------------
Same here: We use a left join with a window with no grace. The right-hand-side
stream of the the join is empty. With the new implementation, the join won't
emit any record for the duration of the window.

> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Clive Cox
> Priority: Major
>
> With the fix in https://issues.apache.org/jira/browse/KAFKA-10847 records
> will be emitted after the grace period but only when a new record is
> processed. This means its possible to wait for arbitrary long time for a
> record to be emitted.
> This also means one can not recreate the previous semantics of emitting
> immediately records or even now guaranteed emitting after the grace period.
