Hi @waynexia and thanks for the contribution. I understand using the JIT to compile expression trees but I don't understand why we would want to compile a logical plan rather than leverage the JIT in the physical plan? Could you explain that some more? The logical plan has the concept of a join but we don't know whether that is a HashJoin, CrossJoin, or SortMergeJoin until we get to the physical plan so I don't see how we could compile anything from the logical plan for joins as one example. -- This is an automated message from the Apache Git Service.
