The following tests in JoinFieldedPipesPlatformTest fail when the join is executed with a DOP > 1:

  • testJoinOuterInner()
  • testJoinOuter()
  • testJoinMixed()

Executing right/full outer joins with Broadcast strategies is not possible.
This issue can be solved by adding Hash-OuterJoin support to Flink.

Support for LeftJoin HashJoins has been added.
The remaining join types will be supported once Flink features hash-based execution strategies for full outer joins.
