Actually, getting some luck with RowTypeConstraint. The following works fine:
```
output = (p
| beam.Create([{"num": 1, "name": "a"}, {"num": 2, "name": "b"}])
| beam.Map(lambda el: beam.Row(**el))
.with_output_types(beam.row_type.RowTypeConstraint.from_fields([
('num', int),
('name', str)
]))
| beam.io.StorageWriteToBigQuery(table=table))
```
