Chapter 6. Advanced Queue Features

6.1. Browse-only Queues
复制链接

Queues declared "browse-only" allow subscribers to access them and acquire their messages normally, but message acquisition transparently results only in a browse. The message will remain on the queue, and accessible to other subscribers.
Messages can only be removed from a browse-only queue by some non-acquisition mechanism: for example, when the message's TTL (time-to-live) duration expires.
The spout and drain programs are part of the client libraries package and when installed can be found at: 
/usr/share/doc/python-qpid-${version}/examples/api/

Here is an example of the creation and use of a browse-only queue by the spout and drain clients. 
./spout \
      -c 10 \
      --broker "localhost:${PORT}" \
      'q; {create: always, node:{type:queue , x-declare:{arguments:{"qpid.browse-only":1}}}}' \
      "All work and no play makes Mick a dull boy."

      ./drain --broker 'localhost:${PORT}' 'q'
