Attribute
Name	Description
`proto_descriptor`	`google.protobuf.descriptor_pb2.DescriptorProto` Descriptor for input message. The provided descriptor must be self contained, such that data rows sent can be fully decoded using only the single descriptor. For data rows that are compositions of multiple independent messages, this means the descriptor may need to be transformed to only use nested types: https://developers.google.com/protocol-buffers/docs/proto#nested For additional information for how proto types and values map onto BigQuery see: https://cloud.google.com/bigquery/docs/write-api#data_type_conversions
