lua-resty-beanstalkd - non-blocking beanstalkd lib for ngx_lua.
This library is considered experimental and still under active development.
The API is still in flux and may change without notice.
Copy the lib/resty/beanstalkd.lua file to the location:
/usr/local/openresty/lualib/resty/beanstalkd.lua
This library requires an nginx, the ngx_lua module support beanstalk commands: use, put, watch, reserve, delete, release, bury, kick, peek, stats-tube, list-tubes
