Extremely basic setup to raise my questions: 1. I have a queue based setup with a single producer and a single consumer. 2. Connections are made through a JMS client on both ends. 3. Default configurations overall. 4. For the receiving side I have an implementation of Listener where I ingest messages through onMessage().
So, whenever onMessage() gets me a message, this basically comes from the prefetch buffer which has already received the messages from the broker, but the acknowledgement will be sent after completion of onMessage() method. Also, this prefetch folder is filled before-hand after the atleast 50% messages in it are consumed and acknowledged. Questions: 1. Is some internal service in activemq jar invoked that connects to and requests data from queue? 2. I have read at multiple locations that activemq(and JMS too i think) does not employ polling to get data. Instead, messages are pushed to the receiver. Is this correct? If so, how is the data pushed without requesting for it. Is it through dedicated websocket channel(s)? -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
