Review comment:
Yes, I agree. But Gradle complains during build that there is a missing
setter. Is there a way of circumventing it?
The `PViewsStore` will be skipped completely. As a conclusion of mutual
discussion.

> If for LeftJoin is used BroadcastHashJoinTranslator then from right side is
> created PCollectionView (as sideInput).
> If we use right side in multiple joins then PCollectionView is created
> multiple times which is not optimal behavior.
> Eg.
> {code:java}
> LeftJoin.of(left, right)..
> LeftJoin.of(anotherLeftPcollection, right)..
> {code}
> For example it will happen when we want to solve skew Join.
