---------------------------------

             Summary: left/outer joins can wait indefinitely for emitted record with suprious record fix
                 Key: KAFKA-13813
                 URL: https://issues.apache.org/jira/browse/KAFKA-13813
             Project: Kafka
          Issue Type: Bug
            Reporter: Clive Cox


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.
