I have an application in Django, that needs to send a large number of emails to users in various use cases. I don't want to handle this synchronously within the application for obvious reasons.
Has anyone any recommendations for a message queuing server which integrates well with Python, or they have used on a Django project? The rest of my stack is Apache, mod_python, MySQL.
Message queues can significantly simplify coding of decoupled applications, while improving performance, reliability and scalability.
Implementing messages queues One thing to note is that decoupling of systems with message queues increases the complexity of the system's architecture, so that's one trade-off you will need to consider.
Using Shared Memory or Message Queues depends on the need of the application and how effectively it can be utilized. Writing into the shared memory by one process and reading from the shared memory by another process. As we are aware, reading can be done with multiple processes as well.
Queues are real time in nature If your subscribers pick messages off the queue at the rate they are added, then the additional latency added should be in the low milliseconds. In practical terms, a queue does not add latency.
In your specific case, where it's just an email queue, I wold take the easy way out and use django-mailer. As a nice side bonues there are other pluggable projects that are smart enough to take advantage of django-mailer when they see it in the stack.
As for more general queue solutions, I haven't been able to try any of these yet, but here's a list of ones that look more interesting to me:
So far I have found no "nice" solution for this. I have some more strict soft realtime requirements (taking a picture from a cardboard box being labeled) so probably one of the approaches is fast enough for you. I assume emails can wait for a few minutes.
So far I haven't tried RabbitMQ and XMPP/ejabebrd for handling the problem but they are on my list of next things to try. RabbitMQ got decent Python connectivity during 2008 and there are tons of XMPP libraries.
But perhaps all you need is a correctly configured mailserver on the local machine. This probably would allow you to dump mails synchronously into the local mailserver and thus make your whole software stack much more simple.
