General management and processing of queues.

This runner facilitates interacting with various queue backends such as the
included sqlite3 queue or the planned AWS SQS and Redis queues

The queue functions such as `insert`, `delete`, and `pop` can be used for
typical management of the queue.

The `process_queue` function pops the requested number of items from the queue
and creates a Salt Event that can then be processed by a Reactor. The
`process_queue` function can be called manually, or can be configured to run on
a schedule with the Salt Scheduler or regular system cron. It is also possible
to use the peer system to allow a minion to call the runner.

This runner, as well as the Queues system, is not api stable at this time.

There are many things that could potentially be done with queues within Salt.
For the time being the focus will be on queueing infrastructure actions on
specific minions. The queues generally will be populated with minion IDs.  When
the `process_queue` runner function is called events are created on the Salt
Event bus that indicate the queue and a list of one or more minion IDs. The
reactor is set up to match on event tags for a specific queue and then take
infrastructure actions on those minion IDs. These actions might be to delete
the minion's key from the master, use salt-cloud to destroy the vm, or some
other custom action.

General management and processing of queues.
============================================

This runner facilitates interacting with various queue backends such as the
included sqlite3 queue or the planned AWS SQS and Redis queues

The queue functions such as `insert`, `delete`, and `pop` can be used for
typical management of the queue.

The `process_queue` function pops the requested number of items from the queue
and creates a Salt Event that can then be processed by a Reactor. The
`process_queue` function can be called manually, or can be configured to run on
a schedule with the Salt Scheduler or regular system cron. It is also possible
to use the peer system to allow a minion to call the runner.

This runner, as well as the Queues system, is not api stable at this time.

There are many things that could potentially be done with queues within Salt.
For the time being the focus will be on queueing infrastructure actions on
specific minions. The queues generally will be populated with minion IDs.  When
the `process_queue` runner function is called events are created on the Salt
Event bus that indicate the queue and a list of one or more minion IDs. The
reactor is set up to match on event tags for a specific queue and then take
infrastructure actions on those minion IDs. These actions might be to delete
the minion's key from the master, use salt-cloud to destroy the vm, or some
other custom action.

Queued runners
==============

Using the Salt Queues, references to the commandline arguments of other runners
can be saved to be processed later.  The queue runners require a queue backend
that can store json data (default: :mod:`pgjsonb <salt.queues.pgjsonb_queue>`).

Once the queue is setup, the `runner_queue` will need to be configured.

.. code-block:: yaml

    runner_queue:
      queue: runners
      backend: pgjsonb

.. note:: only the queue is required, this defaults to using pgjsonb

Once this is set, then the following can be added to the scheduler on the
master and it will run the specified amount of commands per time period.

.. code-block:: yaml

    schedule:
      runner queue:
        schedule:
          function: saltutil.runner
          minutes: 1
          args:
            - queue.process_runner
          kwargs:
            quantity: 2

The above configuration will pop 2 runner jobs off the runner queue, and then
run them.  And it will do this every minute, unless there are any jobs that are
still running from the last time the process_runner task was executed.
