I'm trying to send a X?-GB large file as a stream to an ActiveMQ queue for processing.
I know ActiveMQ supports streams, and so does camel-jms, but nothing I try to set on the queue seems to make any difference. The only thing that changes is turning off stream caching results is a "stream closed" exception instead.
I am open to using a processor or custom class (as long as resources get cleaned up), but this should be possible from the blueprint. How do I properly process a large file through camel-activemq without getting an OutOfMemoryError?
Using
- servicemix-7.0.0
- camel-2.16.4
- activemq-5.14.3
Here is my camel blueprint
<?xml version="1.0" encoding="UTF-8"?>
<blueprint

Here is the error I keep getting
