With careful design, the optimizer could hopefully avoid bad plans, although most likely the result would be sub-optimal. Without exhaustive search, it is not always possible to get the optimal plan. WebMachine learning (ML) is becoming a core component in query optimizers, e.g., to estimate costs or cardinalities.
