Virtual predicates #669

Open dennwc opened 6 years ago

dennwc commented 6 years ago

Use #668 to store queries in database. Next, allow to register virtual predicates that refer these queries. Shapes optimizer will run a rewrite pass to detect predicates that are registered as virtual and will add a specified subquery to the tree. Will require #667 to be implemented.
