Subject Need design inputs on programmatic management of large number of queues
Date Fri, 30 Oct 2009 09:00:55 GMT

All,

I need some design guidance.

We are implementing a file-transfer system that transfers files from agent
software installed on customer machines into a central network (or to other
agents in P2P fashion) over ActiveMQ. The files are transferred as
binary-chunks [32K size].

We want to isolate each individual data-transfer using a dedicated queue.
The dedicated queue will be created before the start of the transfer and
dropped at the end of the transfer.

The reason why we chose a dynamic multi-queue architecture is because
1) We dont have to apply any filters to identify messages intended for a
particular agents. Because the size of the files could range from a few MB
to a few GB, we foresee performance problems filtering a large number of
messages for a large number of agents.
2) It provides for more isolation of the data of various customers instead
of having them all in one or more predefined queues.

The questions I have are
1) Is this an agreeable JMS practice? Since JMS API does not offer any queue
management out of the box.
2) Is this agreeable ActiveMQ practice too? 
3) Will there be any performance problems in storage and management of so
many queues?
4) What other kinds of issues should I expect?
5) Any alternatives that can be suggested for this design?

Many thanks for your kind suggestions.
