<<-HELP
puppet-queue(8) -- Deprecated queuing daemon for asynchronous storeconfigs
========
SYNOPSIS
--------
Retrieves serialized storeconfigs records from a queue and processes
them in order. THIS FEATURE IS DEPRECATED; use PuppetDB instead.
USAGE
-----
puppet queue [-d|--debug] [--help] [-v|--verbose] [--version]
DESCRIPTION
-----------
This application runs as a daemon and processes storeconfigs data,
retrieving the data from a stomp server message queue and writing it to
a database. It was once necessary as a workaround for the poor performance
of ActiveRecord-based storeconfigs, but has been supplanted by the PuppetDB
service, which gives better performance with less complexity.
For more information, see the PuppetDB documentation at
http://docs.puppetlabs.com/puppetdb/latest
OPTIONS
-------
Note that any setting that's valid in the configuration
file is also a valid long argument. For example, 'server' is a valid
setting, so you can specify '--server <servername>' as
an argument.
See the configuration file documentation at
http://docs.puppetlabs.com/references/stable/configuration.html for the
full list of acceptable parameters. A commented list of all
configuration options can also be generated by running puppet queue with
'--genconfig'.
* --debug:
Enable full debugging.
* --help:
Print this help message
* --verbose:
Turn on verbose reporting.
* --version:
Print the puppet version number and exit.
EXAMPLE
