Subject [jira] [Created] (QPID-8202) [Broker-J][AMQP 0-9] Large flowed to disk message can be re-loaded from store for every content chunk sent to the client

--------------------------------

             Summary: [Broker-J][AMQP 0-9] Large flowed to disk message can be re-loaded from
store for every content chunk sent to the client
                 Key: QPID-8202
                 URL: https://issues.apache.org/jira/browse/QPID-8202
             Project: Qpid
          Issue Type: Improvement
          Components: Broker-J
    Affects Versions: qpid-java-broker-7.0.4, qpid-java-broker-7.0.1, qpid-java-broker-7.0.0,
qpid-java-broker-7.0.2, qpid-java-broker-7.0.3
            Reporter: Alex Rudyy
             Fix For: qpid-java-broker-7.0.5, qpid-java-broker-7.1.0


When large message cannot fit in one frame it is sent in multiple blocks. Currently, the flowed
to disk message is reloaded from store and evicted from memory on sending every block. As
result, the broker consumption performance is very slow. Only AMQP  protocols 0-8..0-91 are
affected by the issue
