The first is the "logical" plan as you mentioned, and the latter is the physical one. Based on that, if the "DAG" path is too rigid to adapt to cost-based optimization, we might choose another solution for the architecture of the execution plan. Yes. After some investigation, I found tree-structured logical plan may be more suitable for our cases, - use rule-based optimization for logical plan - generate multiple physical plans and choose the best one based on cost-based optimizer while DAG is still feasible for a physical plan. I will continue working on this PR. -- This is an automated message from the Apache Git Service.
