      Description

      The ASTJoinOrderOptimizerByType deserves improvement, both in terms of performance (some optimizations could be improved) as well as correctness (see the list of tickets listed below). A proposal for refactoring is proposed in the google doc "Join Order Optimization". This includes the automatic detection where to best schedule service calls to guarantee that incoming variables are bound and outgoing variables are not (cf. BLZG-40).
