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

>
> As [~h...@pinterest.com] 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.
