There are plenty of tutorials about memory management with RabbitMQ. There are mechanisms for setting the high watermark for memory to throttle producers. You could look at the database backend for django-kombu. It might have a smaller footprint. django-ztask looks interesting, but you

We're using MySQL 5 (don't know off the top of my head what specific release). I don't think a master/slave DB configuration is something we can manage to set up at this point. Querysets are fetched from the database in chunks, right? I imagine that the select itself is actually quite quick,

Re: Simple task dispatching (How heavy is celery + RabbitMQ)

Celery has a bunch of alternative brokers, depending on your constrains you may not need something as "heavy" as RabbitMQ, you could for example use db broker if you don't have many tasks, it is slower but does not add a new server (apart from celery) to your stack, other option is to use Redis as

Re: Simple task dispatching (How heavy is celery + RabbitMQ)

You don't need to roll your own... have a look at https://github.com/dmgctrl/django-ztask It's based on ZeroMQ and really lightweight compared to any alternative with a broker (yes, it's brokerless but that's a good thing I think for most use cases which don't really need a broker). -- You
