Whole-dataflow optimization

A dataflow may contain multiple views, each of which may only be optimized locally. However, information like demand and predicate pushdown can be applied across views once we understand the context in which the views will be executed.


  • Extra information about the dataflow. This is not going to be shipped, but has to be processed in other ways, e.g., showing notices to the user, or saving meta-information to the catalog.
