| * Datetimes are converted to UTC seconds. |
| * Decimals are converted to floats. |
| * Dates are converted to ISO formatted string if given schema_type is |
| DATE, or UTC seconds otherwise. |
| * Binary type fields are converted to integer if given schema_type is |
| INTEGER, or encoded with base64 otherwise. Imported BYTES data must |
| be base64-encoded according to BigQuery documentation: |
