LRO endpoint to batch process many documents. The output is written to Cloud Storage as JSON in the [Document] format.

Parameters

Name	Description
request	`protos.google.cloud.documentai.v1.IBatchProcessRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.
