> Currently it's not very clear how we should abstract data source v2 API. The abstraction should be unified between batch and streaming, or similar but have a well-defined difference between batch and streaming. And the abstraction should also include catalog/table.
> An example of the abstraction:
> {code}
> batch: catalog -> table -> scan
> streaming: catalog -> table -> stream -> scan
> {code}
