I’m happy to announce the release of beanstalkd 0.5.

This is the very first public release. In the future I’ll confine  
release announcements to the beanstalk mailing list.

## WHAT IS BEANSTALKD?

Beanstalkd is a fast, distributed, in-memory workqueue service. Its  
interface is generic, but is intended for use in reducing the latency  
of page views in high-volume web applications by running most  
time-consuming tasks asynchronously.

Philotic, Inc. developed beanstalkd to improve the response time for  
the Causes on Facebook ([Log into Facebook](http://apps.facebook.com/causes/)) application  
(with over 9.5 million users). Beanstalkd drastically decreased the  
average response time for the most common pages to a tiny fraction of  
the original and dramatically improved the user experience.

Stay tuned for a Rails plugin called Async Observer that will make  
using beanstalk in your Rails project a snap!

## OUR FEW URLS

Download the 0.5 tarball and learn all about beanstalk:  
[http://xph.us/software/beanstalkd/](http://xph.us/software/beanstalkd/)

Talk about beanstalk development or use at:  
[http://groups.google.com/group/beanstalk-talk](http://groups.google.com/group/beanstalk-talk)

## HOW TO RUN IT

First, run beanstalkd on two or three machines. There is no  
configuration file and only a handful of command-line options.

$ ./beanstalkd -d -l 10.0.1.5 -p 11300

This starts up beanstalkd as a daemon listening on address 10.0.1.5,  
port 11300. If you want to spy on what beanstalkd is doing, recompile  
it in debug mode.

## HOW TO USE IT

Here’s an example in Ruby. First, have one process put a job into the  
queue:

beanstalk = Beanstalk::Pool([‘localhost:11300’])  
…  
beanstalk.put(‘hello’)

Then start another process to take jobs out of the queue and run them:

beanstalk = Beanstalk::Pool([‘localhost:11300’])  
loop do  
j = beanstalk.reserve  
puts j.body # prints “hello”  
j.delete  
end

## DEPENDENCY

Beanstalkd requires libevent. It was developed with libevent 1.3b, but  
it may work with other versions.

[http://monkey.org/~provos/libevent/](http://monkey.org/~provos/libevent/)

## KNOWN BUGS

- The min heap data structure is not dynamically-sized. This means a  
fixed hard limit on the number of ready jobs (by default set to  
around 16 million).

- The policy of signalling errors by closing the connection is wrong.  
The server should send a helpful error response whenever possible  
and only close the connection as a last resort.

j’ai pas trop compris ce que c’est… c’est pour mettre des taches à  
exécuter en parrallèle du site lui-meme, dans le style de backgroundrb ?
