> The RecordBatchReader interface is a key abstraction for the C stream API.
> There is no great way today to convert a Table (or an iterable of batches) to
> a RecordBatchReader.
> DuckDb is currently doing this by wrapping the Table in an in-memory dataset
> and consuming it with a scanner but this has considerable overhead
> (especially if the Table has many batches).
> Alternatively, we could add bridge methods to export a table to a stream but
> I think this approach would be simpler.
