Hello, Currently the RabbitConsumer, when the autoAck configuration is set to false delivers 1 message, waits until the flow has finished and then acknowledges it. After it finishes with the first message is able to continue with the next message. This does not scale well if you want to support multiple inflight exchanges. The only solution around it, is to add more consumers.
I tested by applying the following changes https://github.com/maragud/camel-rabbitmq/commit/9f695c1dff05b8e4cc1004ea242c210fd10e59b1 which could deliver up to the number of prefetched messages to each consumer without receiving a acknowdgement. This way, a route that uses 100 concurrent consumers could be converter to a route that uses 1 consumer with prefetchCount=100 -- Andreas Maragudakis
