[jira] [Created] (ARTEMIS-366) MQTT Retain Messages use message.copy()

Martyn Taylor created ARTEMIS-366:
-------------------------------------

             Summary: MQTT Retain Messages use message.copy()
                 Key: ARTEMIS-366
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-366
             Project: ActiveMQ Artemis
          Issue Type: Improvement
            Reporter: Martyn Taylor


The MQTT Retain implementation uses special address to handling retained messages.  Any retained message received will be forwarded to the appropriate address and a copy sent to the special retain address.

Since we are not uses pooled buffers, the buffer allocation for copies of retained messages can be high.  We should try to use a message reference instead of copy.
