The uploader is co-located with our low-latency app. inside the JVM.  To control latency, we must throttle the uploader.   Our best workaround involves resorting to reflection in order to install `HttpRequest` interceptor which effectively wraps `HttpContent` with a throttled `OutputStream`; e.g.,\r\n\r\n```\r\nObject storageRpc = FieldUtils.getField(storage.getClass(), \"storageRpc\", true).get(storage);\r\nObject serviceStorage = FieldUtils.getField(storageRpc.getClass(), \"storage\", true).get(storageRpc);\r\nObject requestFactory = FieldUtils.getField(serviceStorage.getClass(), \"requestFactory\", true).get(serviceStorage);\r\nField initializerField = FieldUtils.getField(requestFactory.getClass(), \"initializer\", true);\r\nObject initializer = initializerField.get(requestFactory);\r\ninitializerField.set(requestFactory, new InterceptingHttpRequestInitializer((HttpRequestInitializer) initializer));\r\n``` ","author":{"url":"https://github.com/srosenberg","@type":"Person","name":"srosenberg"},"datePublished":"2018-08-06T15:43:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":12},"url":"https://github.com/3534/google-cloud-java/issues/3534"}
