> The camel documentation states that there are two ways to acknowledge a Google pubsub message. They are "ackMode=AUTO" and "ackMode=NONE". If the mode is set to NONE, the document states that the "downstream process has to acknowledge explicitly". However there are no examples, or pointers on how to do that.
> The unit tests also do not reflect this scenario. The [AckModeNoneTest.java|https://github.com/apache/camel/blob/master/components/camel-google-pubsub/src/test/java/org/apache/camel/component/google/pubsub/integration/AckModeNoneTest.java] sets the ackMode to NONE, and checks if the message is redelivered, but it doesn't test how to acknowledge the message. This file [AcknowledgeSync.java|https://github.com/apache/camel/blob/master/components/camel-google-pubsub/src/main/java/org/apache/camel/component/google/pubsub/consumer/AcknowledgeSync.java] has the steps to acknowledge, but it's not clear how to do that within a Camel route. It seems to need an class called com.google.cloud.pubsub.v1.stub.SubscriberStub that is passed into it.
