Vineet Garg commented on CALCITE-3011:
--------------------------------------
Fixing this issue in {{AggregateJoinTransposeRule}} doesn't fully fix the wrong
plan. It looks like {{areColumnsUnique}} is returning true for FULL OUTER JOIN
which seems wrong.
> Support outer joins with AggregateJoinTransposeRule
