Hi, We are using activemq to handle our JMS messages, the messages come from different devices with unique device_id and we like to make sure that messages from a specific device , process in order. also we have thousands of devices. I am new on AMQ but we have performance issue and I came across message group concept so I think it can help us but I am just worry that, if we use multiple consumers and use that device_id as our JMSXGroupID, basically for example all messages from device_id 205 and 105 will all go to the consumer1 , and all messaged from 102 and 202 go to consumer2 and so on, now think about this scenario that a message form 105 go into the consumer1 and it take long to get processed, then a message from 205 come , we dont want it to wait because although they are belong to same consumer but they are for different devices and we dont care if they are not in a same order! so is there any mechanism that we can check and see which device_id make consumer busy , so if new message comes in, we first check see if it has the same device_id or not! if not we send this message to a another consumer that is not too busy but if it has a same device_id then it has to wait in the queue of that consumer because of the order issue.
Thank you for any help and suggestion in advnace -- View this message in context: http://activemq.2283324.n4.nabble.com/Message-Group-tp4680478.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
