Hi,
We have a flow picking up messages from a JMS queue. The messages have to be processed in sequence in which it is put in the JMS queue.
While the flow works fine, sometimes the messages are going out of sequence.
Could anyone pls let me know if this is normal behaviour ? Should we use the sequence node to do the sequencing ?
Thanks. |

Hi next,
If you have more than 1 instance of your flow running(it seems to be the case), yes, it is the normal behaviour.
For example, if your JMS queue has 100 messages and there are 10 instances of your message flow deployed and running in the Broker, they will be processed in parallel, so you can't guarantee the processing messages order.
You might be able to use a Resequence node, found good information here:
