I'm thinking of using `+label` after each `statement ok` and `query` to do some custom extensions over the original sqllogictest syntax. An example here: https://github.com/cmu-db/bustub/blob/85477ace4eb3ff6531ccfb075dbc283ff99dbdf1/test/sql/p3.14-topn.slt#L354-L359 What we can do: *...

In this PR, we redesigned the storage part to: * Firstly, support single insert. * Then, support multiple inserts, while introducing the terminology of RowSet. * The rest as before,...

For example, when I was composing the tutorial for the storage world, I'd want to... * Create a base branch for world-3 * Adding commits * Sometimes, revisit previous commits...

we can (1) collect all table scans from the plan node, (2) in the async context, retrieve the schema, and (3) remove async from schema inference.

- [ ] plan nodes - [ ] rules - [ ] datafusion executors - [ ] runtime data collection

I don't think this task is important because I don't see physical properties very useful when evaluating Datafusion. Sometime later, we should add physical property support for the optimizer framework.

currently, we do not compute upper bound / lower bound for the pruning process. we simply explore the full logical plan space and compute a winner for the physical plan....
