configurationClass in class TypedSchemaTransformProvider<BigQueryFileLoadsWriteSchemaTransformConfiguration>

from

protected SchemaTransform from(BigQueryFileLoadsWriteSchemaTransformConfiguration configuration)

Returns the expected SchemaTransform of the configuration.

from in class TypedSchemaTransformProvider<BigQueryFileLoadsWriteSchemaTransformConfiguration>

identifier

public java.lang.String identifier()

Implementation of the TypedSchemaTransformProvider identifier method.

inputCollectionNames

public java.util.List<java.lang.String> inputCollectionNames()

Implementation of the TypedSchemaTransformProvider inputCollectionNames method. Since a single is expected, this returns a list with a single name.
