> BigQuery should be accepting string values here - formatting as an integer
should be a performance change only
I think it's a _correctness_ issue rather than performance change. BigQuery
Storage Write API _rejects_ date/timestamp encoded in string format. In this
commit
[b56823d1d213adf6ca5564ce1d244cc4ae8f0816](https://github.com/liu-du/beam/commit/b56823d1d213adf6ca5564ce1d244cc4ae8f0816),
I used existing conversion (use string value for date/timestamp columns) and
add an integration test to write date/timestamp using protobuf string values,
the error I get is:
`INVALID_ARGUMENT: The proto field mismatched with BigQuery field at
Da40f0078_2574_4708_b66f_79eb0e516c43.datevalue, the proto field type string,
BigQuery field type DATE Entity`
