But how could activemq help. Isn't it camel that is responsible for transaction demarcation? > What is the reason for this? The FUSE tuning guide says: "Even if you have to pay the performance cost of XA transactions - using batching (processing and sending many messages in a single transaction (JMS or XA) will boost performance considerably. This is because you share the synchrony cost (the waiting for things to be written and sync'd to disk) across many many messages." That's exactly what we want to achieve.
