@mustafasrepo @ozankabak My original plan was try to leverage the top-down process to achieve two goals: 1) Simply the optimization process, make it easily to understand 2) Can do all the sort optimizations in one pass, But when I start the implementation and testing I realize that it is quite hard to achieve the two goals at same time. I think the new implementation is the hybrid of bottom-up and top-down approach but it is more complex. I accept that in the current phase, we combine the two approaches to offer full functionality. But in future I think we should still pursue the goal to offer the full functionality in a pure top-down approach. -- This is an automated message from the Apache Git Service.
