About |
Beanstalk is a simple, fast work queue.
Its interface is generic, but was originally designed for reducing the latency of page views in high-volume web applications by running time-consuming tasks asynchronously.
{% for post in site.posts limit:1 %}
[{{ post.title }}]({{ post.url }})
{% endfor %}
First, run beanstalkd on one or more machines. There is no configuration
file and only a handful of command-line options.
{% highlight bash %} $ ./beanstalkd -l 10.0.1.5 -p 11300 {% endhighlight %}
This starts up beanstalkd listening on address 10.0.1.5, port 11300.
For more information on how to run beanstalkd as a background service,
in production, see the adm directory.
Here's an example in Ruby -- see the client libraries to find your favorite language.
First, have one process put a job into the queue:
{% highlight ruby %} beanstalk = Beanstalk::Pool.new(['10.0.1.5:11300']) beanstalk.put('hello') {% endhighlight %}
Then start another process to take jobs out of the queue and run them:
{% highlight ruby %} beanstalk = Beanstalk::Pool.new(['10.0.1.5:11300']) loop do job = beanstalk.reserve puts job.body # prints "hello" job.delete end {% endhighlight %}
Philotic, Inc. developed beanstalk to improve the response time for the Causes on Facebook application (with over 9.5 million users). Beanstalk decreased the average response time for the most common pages to a tiny fraction of the original, significantly improving the user experience.
