Hi @marmbrus,
first i think this change is not doing query planning because
1 query planning is to convert a logical plan to spark plan (correct me if
i misunderstanding)
2 here i make a new logical node from RunnableCommand to LocalRelation
second, your suggestion is really useful, how about change as following:
1 add a rule to optimizer to transform from RunnableCommand to LocalRelation
2 remove ExecutedCommand, since
```
case logical.LocalRelation(output, data) =>
LocalTableScan(output, data) :: Nil
```
will transform LocalRelation to LocalTableScan
