macro class fromSchema extends Annotation with StaticAnnotation
Macro annotation for a BigQuery schema.
Generate case classes for a BigQuery schema. Note that schema must be a string literal of the
JSON schema with optional .stripMargin at the end. For example:
@BigQueryType.fromSchema(
"""
|{
| "fields": [
| {"mode": "REQUIRED", "name": "f1", "type": "INTEGER"},
| {"mode": "REQUIRED", "name": "f2", "type": "FLOAT"},
| {"mode": "REQUIRED", "name": "f3", "type": "STRING"},
| {"mode": "REQUIRED", "name": "f4", "type": "TIMESTAMP"}
| ]
|}
""".stripMargin) class MyRecordAlso generate a companion object with convenience methods.
