Work Description: mareksimunek commented on pull request #7399: [BEAM-6350] Reuuse PCollectionView when created in translators
URL: https://github.com/apache/beam/pull/7399
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.
