+# Design Rationale
+
+Push vs Pull Based
+
+|Push| Pull|
+|----| ----|
+|Improves cache efficiency by removing control flow logic | Easier to implement |
+|Forking is efficient: You push a thing only once   |Operators like LIMIT make their producers aware of when to stop running (Headache for the optimizer)|
+|Parallelization is easier|Parallelization is harder|
