---------------------------------
Summary: Incorrect validation check on maintenance period with join window
size (was: RocksDBWindowStore should guarantee a single window locates
completely in one segment)

> Key: KAFKA-3658
> URL: https://issues.apache.org/jira/browse/KAFKA-3658
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Guozhang Wang

> Fix For: 0.10.0.1
>
>
> As [[email protected]] found out, the current implementation of
> {{RocksDBWindowStore}} does not guarantee a single window locates completely
> in one segment, and hence when we expiring a segment, that would result in
> partial window expiration (i.e. some records of the window are dropped, while
> some others are still available for queries). We need to fix this issue in
> setting the segment size to consider the window size.
> Another minor issue is that retention size should be validated correctly to
> be no less than the window size.
