Hi, If you set the option of autoAck is false, Camel will send the acknowledgement to RabbitMQ when the exchange is processed.
If you want to do it in the batch mode, you may need to change the RabbitMQConsumer, but I’m not sure how can get the channel if you want to send the acknowledgement in your custom bean. -- Willem Jiang Red Hat, Inc.
