[rabbitmq-discuss] [Q] periodic queue delivery

[Alexis Richardson]

Chuck

RabbitMQ does not (yet) support any internal behaviours where time is
a parameter.

This points you to sampling and batching at the:

* Client
* "Proxy" (see Client)
* Plugin

The first approach is just fine for many cases.  The last has the
strongest fate sharing properties.
