For 03-01, now only the last inserted data could be read. Is it a bug or by design?

For the test, can we add some features to sqllogictest for testing durability?

Yes, it's by design. We only support multi-insert after introducing the concept of RowSet.

I don't think there's need to do this. Firstly, we don't have manifest. Even if all data are on disk, we won't know there are after restart. Secondly, we don't have mem table, so there's no possibility that data are read from memory.
