GetGcpVisionAnnotateImagesOperationStatus is designed to periodically check the statuses of image annotation operations. This processor should be used in pair with StartGcpVisionAnnotateImagesOperation Processor. An outgoing FlowFile contains the raw response returned by the Vision server. This response is in JSON json format and contains a google storage reference where the result is located, as well as additional metadata, as written in the Google Vision API Reference document.
