-----------------------------------
Summary: Reuuse PCollectionView when created in translators
Key: BEAM-6350
URL: https://issues.apache.org/jira/browse/BEAM-6350
Project: Beam
Issue Type: Improvement
Components: dsl-euphoria
Affects Versions: 2.11.0
Reporter: Marek Simunek
Assignee: David Moravek
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.
