Commit c17d978d02dc0f1624970f447e2d1e3572b62f35 in qpid-cpp's branch
refs/heads/master from Kim van der Riet
[ https://gitbox.apache.org/repos/asf?p=qpid-cpp.git;h=c17d978 ]
QPID-8430: Reduce memory consumption of AMQP 0-10 messages when rerouted by
preventing deep copy of non-persistent messages. AMQP 1.0 memory consumption is
unchanged.
> [qpid-cpp] Excessive memory use when rerouting messages
> -------------------------------------------------------
>
> Key: QPID-8430
> URL: https://issues.apache.org/jira/browse/QPID-8430
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Reporter: Kim van der Riet
> Assignee: Kim van der Riet
> Priority: Major
>
> When a message is rerouted several times, the broker's used memory increases
> rapidly. This is counter-intuitive, considering that the messages themselves
> are only passing from one queue to another. There is no evidence of a leak,
> however, only a large growth in consumed memory.
> An investigation has shown that the process of clearing traces from the
> message when rerouting (whether they exist or not) causes the message and its
> frames to be copied (for reasons of avoiding locks on the message, which can
> affect performance).
