What's changed and what's your intention?

  • Plan nested loop temporal join for inner and cross join.
  • Add e2e and planner test.

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.
