> If {{DATE}} type is specified in schema, {{BigQueryIO}} with Storage Write API may fail with the following error:
> {quote}Got error com.google.api.gax.rpc.InvalidArgumentException: io.grpc.StatusRuntimeException: INVALID_ARGUMENT: The proto field mismatched with BigQuery field at <table>, the proto field type string, BigQuery field type DATE Entity: <write_stream_name>
> ...
> {quote}
> {{DATE}} type in BEAM for BigQuery is converted to {{string}} in proto request [1], while BigQuery Storage Write API requires an integer type for {{DATE}} type in BigQuery [2].
> A workaround is to use {{INTEGER}} in BEAM and manually compute the number of days since epoch.
> Actually, a feature request to BigQuery is filed at [3]. If it's implemented, we can use {{DATE}} type successfully.
