- context, it really is everything\nin engineering web applications its all about the milliseconds\ntasks like …. take time\nthey not only take time, often they are supporting tasks\nthings that do not directly impact servicing a request form the user\n

- users are fickle\ni like to think that a web application should focus on responding as fast possible to the request form its user\nif not they will leave\nso, any operation thats not directly related to the request can and probably should go elsewhere\n\n
- where ?\nbackground jobs … whats that\nthink asynchronous\nsupermarket shelves are stacked in the night to ensure shoppers can walk in get there things and walk out\nit would be a sucky experience to walk in and wait for them to stock the milk before you could buy it\n

- there are various systems to do background/async processing\nbackgroundjob is a zero admin background priority queue for rails\ndelayedjob is similar with the advantage that it doesn’t load the entire rails env into memory\nbeanstalk is a simple, fast work queue. its interface is generic, was designed for increase response times for high-volume web apps\ngearman is quite similar to resque as it supports persistant queues, is open source, fault tolerant and is distributed\n

- resque supports prioritising jobs by prioritising queues against each other\njobs are persisted to queues as JSON objects and the queues are stored in redis as lists\na nice web interface, a sinatra app, is also included for monitoring the workers\nplugin system using a event framework for events like after_fork, before_fork etc \n

- this is a little tangent, but i quickly want to talk about redis\nit’s a key-value store, all its operations are atomic and O(1) meaning they will always complete in a constant amount of time\nthis means speed and its really important when you want to set and forget\n\n

- so, how does it do what it does ?\nas a user of the resque library in your app you essentially interact with redis\nwhen you ask resque to queue up a job, it will push it onto the queue in redis\na resque worker comes along at some point in time and pops a job of the queue and forks that into its own process and runs the job\n\n
