The 'size' in the statistics you see is the total number of messages which have been sent to this topic. Unsurprisingly, for topics it is the same as enqueueCount.
I can only image these numbers to differ when you have a queue instead of topic. Then, the size represents the number of message in the queue, which haven't yet been picked up (enqueueCount - dequeueCount = size). In a Topic you don't have the concept of messages which have to be picked up. If nobody is subscribed to a topic the message sent there is dropped. This is not necessarily the case for a Queue. Therefore the size indicator makes sense. walec51 wrote: > > Hello, > > I'm looking and the topic xml file generated by the web admin of ActiveMQ > 5.3 and I see that my topic's size are always equal to the number on > enqueued messages.
