beanstalkd - simple, fast work queue

Beanstalkd  is  a  simple work-queue service. Its interface is generic, though it was originally designed
       for reducing the latency of page views in high-volume web applications by  running  time-consuming  tasks
       asynchronously.

       When  started,  beanstalkd  opens a socket (or uses a file descriptor provided by the init(1) system, see
       #ENVIRONMENT) and listens for incoming connections. For each connection, it reads a sequence of  commands
       to  create,  reserve,  delete,  and  otherwise  manipulate  "jobs",  units  of  work to be done. See file
       doc/protocol.txt in the beanstalkd distribution for a thorough description of the meaning and  format  of
       the beanstalkd protocol.

LISTEN_PID, LISTEN_FDS
              These variables can be set by init(1). See sd_listen_fds(3) for details.

-bpath
              Use  a  binlog to keep jobs on persistent storage in directory path. Upon startup, beanstalkd will
              recover any binlog that is present in path, then, during normal operation,  append  new  jobs  and
              changes in state to the binlog.

       -fms  Call  fsync(2)  at  most once every ms milliseconds. Larger values for ms reduce disk activity and
              improve speed at the cost of safety. A power failure  could  result  in  the  loss  of  up  to  ms
              milliseconds of history.

              A ms value of 0 will cause beanstalkd to call fsync every time it writes to the binlog.

              The default behavior is to sync every 50 ms.

              (This option has no effect without -b.)

       -F     Never call fsync(2). Equivalent to -f with an infinite ms value.

              (This option has no effect without -b.)

       -h     Show a brief help message and exit.

       -laddr
              Listen on address addr (default is 0.0.0.0).

              When  addr  starts  with  "unix:", the unprefixed value of it will be used as the local filesystem
              path to create a UNIX socket instead of a TCP socket. In  this  case  the  value  of  -p  will  be
              ignored.

              (Option -l has no effect if sd-daemon(5) socket activation is being used. See also #ENVIRONMENT.)

       -pport
              Listen on TCP port port (default is 11300).

              (Option -p has no effect if sd-daemon(5) socket activation is being used. See also #ENVIRONMENT.)

       -sbytes
              The size in bytes of each binlog file.

              (This option has no effect without -b.)

       -uuser
              Become the user user and its primary group.

       -V     Increase  verbosity.  May be used more than once to produce more verbose output. The output format
              is subject to change.

       -v     Print the version string and exit.

       -zbytes
              The maximum size in bytes of a job.

       -c     This flag has no effect. It is kept for historical compatibility only.

       -n     This flag has no effect. It is kept for historical compatibility only.
