Esteemed Perl professionals and enthusiasts alike,

I'm looking for a solution or a product. What I need to do is to scale an application across servers.

The preferred method of doing so would be to send hundreds (or a few thousand) messages to a queue a second, and then whoever is available will grab a message from the queue and process it. The messages are small, just a short string containing a tablename and an ID.

All nodes will have a database connection to the same database, so I am indeed considering implementing this in a database table. But are there better alternatives out there?

I know about these solutions:

• Websphere MQ server - which is interesting but expensive, yet within reach for really large clients.
• Spread - which is not really suited for our purposes, as it sends one copy to each node.
• Spread::Queue - has not been maintained since 2002, not thread-safe, but looks OK otherwise.
• POE - a framework, so I need to create both server and client code.

Are there any I have missed that I should know about? What are your 2c?
