Beanstalkd is a simple to use job queue. It provides a means to create multiple job queues called "tubes". Each tube can store multiple jobs, with varying priorities with the queue. Queue processing is available via a simple TCP socket or via well defined libraries, avaialble at https://github.com/kr/beanstalkd/wiki/client-libraries This module is based upon the beanstalk-client library, available for download at: https://github.com/deepfryed/beanstalk-client Change-Id: I5fe4089a34ab3b39230786d9bbfddafa56715f48remotes/origin/16.0

; Beanstalkd includes the capability of using multiple queues at the same time, with priorities.

;
|
||||||
|
; This module requires that your server has the beanstalk-client library installed. The library
|

|
; can be downloaded from - https://github.com/deepfryed/beanstalk-client
