Hi Justin, Thank you for your reply. I had no way to get large messages support using Camel routes with Camel-amqp endpoint. With Camel-amqp, using qpid connection (org.apache.qpid.jms.JmsConnectionFactory), messages over the default 100kb weren’t processed. Camel went to an infinite loop printing this error at each iteration:
2023-08-23 11:07:18 org.apache.camel.RuntimeCamelException: Failed to extract body due to: javax.jms.MessageNotWriteableException: Message properties are read-only. Message: JmsBytesMessage { org.apache.qpid.jms.provider.amqp.message.AmqpJmsBytesMessageFacade@39dd152c<mailto:org.apache.qpid.jms.provider.amqp.message.AmqpJmsBytesMessageFacade@39dd152c> } 2023-08-23 11:07:18 at org.apache.camel.component.jms.JmsBinding.extractBodyFromJms(JmsBinding.java:174) 2023-08-23 11:07:18 at org.apache.camel.component.jms.JmsMessage.createBody(JmsMessage.java:234) Switching to core the messages over 100k were handled but no way to change the minimum large messages default value. From the support I got from Camel mailing list there is no other way than using Camel-jms to have full large messages support: “I am afraid that in order to use minLargeMessageSize you need to use *camel-jms* component and *artemis-jms-client* as jms implementation, because camel-amqp uses *qpid-jms-client.*If you have some time, you can take a look to camel-jms” This force us to use the Artemis connection factory (org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory), in our clients, to connect to the broker, decreasing the generality we like to have on our opensource project. I’m still testing a working configuration with Camel-jms but I was just wondering if there was a way to disable the large messages support.

This is because clients are free to send messages larger than the configured journal-buffer-size (490KB by default). When that happens the broker has no choice but to treat the message as "large" and stream it to disk rather than storing it in the journal. You can increase the journal-buffer-size to make large messages less likely or even effectively eliminate them depending on your use-case, but using the larger buffer may have an impact on performance. What "difficulties" are you having currently with AMQP, MQTT, & large messages?
