Andrew commented on KAFKA-8315:
-------------------------------
[~ableegoldman] Right, I see what you mean, this loop only goes until the head
is found
[https://github.com/apache/kafka/blob/trunk/streams/src/main/java/org/apache/kafka/streams/processor/internals/RecordQueue.java#L158.]
We do have out of order data in our real data streams, however, it looks like
you are right that it shouldn't affect my {{join-example}} demo, which
reproduces the issue with only ordered data. Any further ideas on why the
{{join-example}} doesnt work?
> Cannot pass Materialized into a join operation - hence cant set retention
> period independent of grace

> The documentation says to use `Materialized` not `JoinWindows.until()`
> ([https://kafka.apache.org/22/javadoc/org/apache/kafka/streams/kstream/JoinWindows.html#until-long-]),
> but there is no where to pass a `Materialized` instance to the join
> operation, only to the group operation is supported it seems.

> [Additional]
> From what I understand, the retention period should be independent of the
> grace period, so I think this is more than a documentation fix (see comments
> below)
