# Short-Description: in-memory workqueue service
# Description:       beanstalk is a simple, fast, queueing server. 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.
