John Roesler commented on KAFKA-8315:
-------------------------------------

[~the4thamigo_uk], The python tests are something different.

I was just talking about the Java classes that are called like 
"WhateverWhateverIntegrationTest". You should be able to run those right from 
the IDE. If you want to run all the streams integration tests, it's `./gradlew 
clean :streams:test`. It will take 7 minutes-ish.

> 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)
