Subject [jira] [Commented] (QPID-6778) [Java Broker] Load message meta data from store into direct memory rather then into heap
Date Mon, 22 Feb 2016 09:31:18 GMT

    [ https://issues.apache.org/jira/browse/QPID-6778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15156675#comment-15156675
] 

Rob Godfrey commented on QPID-6778:
-----------------------------------

I think what we want to do here is to ensure that if any object retains a long-term reference
to a QpidByteBuffer that comes from reading meta data which it may later use for writing to
the wire, it should ensure that the retained QpidByteBuffer is from the direct buffer pool...
e.g. BaiscContentHeaderProperties.populatePropertiesFromBuffer(QpidByteBuffer buffer, int
propertyFlags, int size)

> At the moment Broker keeps message meta data loaded from store  in JVM heap memory. The
direct memory should be used for keeping message meta data.
