Static check the DAG #147
Description
Consider the following edge case:
- You clone table A and B from production
- B depends on A
- Now you remove A's script
- If you refresh B, it will still work on your branch, because you've clone A into it; deleting A's definition didn't delete A's physical table
- The refresh will fail in production
I think the cleanest solution is to be able to do a static analysis of the DAG. If B depends on A, then A needs to have a definition.
