public final class ArrowSchema
extends com.google.api.client.json.GenericJson

Arrow schema as specified in https://arrow.apache.org/docs/python/api/datatypes.html and serialized to bytes using IPC: https://arrow.apache.org/docs/format/Columnar.html#serialization- and-interprocess-communication-ipc See code samples on how this message can be deserialized. This feature is not yet available.

This is the Java data model class that specifies how to parse/serialize into the JSON that is transmitted over HTTP when working with the BigQuery API. For a detailed explanation see: https://developers.google.com/api-client-library/java/google-http-java-client/json
