Review Comment:
I am a little confused on what you mean by "highlight"
1. I decided to include this configuration because it can be tuned by the
users. It was introduced in version `3.2.0` via
[KIP-811](https://cwiki.apache.org/confluence/display/KAFKA/KIP-811%3A+Add+config+repartition.purge.interval.ms+to+Kafka+Streams)
but missed to add in docs?
2. Or did you mean only this last line?
> (Note, unlike `commit.interval.ms`, the default for this value remains
unchanged when `processing.guarantee` is set to `exactly_once_v2`).
I used to same description mentioned in the KIP. I think that this line
avoids a confusion (if exists) since it is related to `commit.interval.ms`. I
am happy to remove this if you think otherwise.
