Claus Ibsen commented on CAMEL-15252: ------------------------------------- Paco C @claetenarurus · 6h @davsclaus CAMEL-15252 receiveMessage method doesn't set ACK_ID header. AckMode=NONE must need this header to do manual ack > Google Pubsub Component manual acknowledgement mode > --------------------------------------------------- > > Key: CAMEL-15252 > URL: https://issues.apache.org/jira/browse/CAMEL-15252 > Project: Camel > Issue Type: New Feature > Components: camel-google-pubsub > Affects Versions: 3.4.0 > Reporter: Ramesh Venkitaswaran > Priority: Major > Fix For: 3.x > > > 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. > -- This message was sent by Atlassian Jira (v8.20.10#820010)
