What's changed and what's your intention?
The LHS is the stream side. RHS is the look up table. LHS will be broadcasted and RHS is no-shuffle.
We currently disallow left outer join because LHS will be broadcasted and nested loop temporal join will produce duplicated records from all parallelism when it has a NULL match.
