Background task queue in ChicagoBoss

[Miguel Benitez]

Hi community,

I have a function that takes a long time to run, so I'd like to execute it in the background, I wonder if there is something like http://www.celeryproject.org/ in chicagoboss?

Any help is appreciated

Why can't you just use a gen_server with an asynchronous callback?

create your gen server, when you need your background processing, use send_event/2 on it and then let it rip... your main process need only have a receive loop in it somewhere and that should do it.

Otherwise if it is a *big* requirement you might use boss_mq as a simple work queue but again the same principle will apply. And there there is RabbitMQ for the big jobs. I love Rabbit! Even as a vegetarian. :)

Is this is response to a web request though??? That could be interesting because you would either have to use a keep-alive (web socket) or once processing is complete, use a POST back to the caller but then the caller needs to be listening for it which means tagging each request with a unique ID etc etc

I like being a systems architect!  ROFLCOPTER etc.

Hope that helps a bit... ask more detailed questions if you like.

Sean.

That might provide some food for thought maybe adapted to boss_mq or something?!

You can use boss_news to run actions if some data changes. also, there is built-in queue called boss_mq, so you can use it for simple tasks without adding any external libraries.
