Native Worker Options
=====================

**Native Workers**, that is *Routers* and *Containers* can be further
configured with ``options``.

Both *Routers* and *Containers* share the following ``options``:

+---------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| option        | description                                                                                                                                                                                                      |
+===============+==================================================================================================================================================================================================================+
| title         | The worker process title (default: "crossbar-worker [router]" or "crossbar-worker [container]")                                                                                                                  |
+---------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| python        | The Python executable to run the Worker with, e.g. /opt/python27/bin/python - this must be an absolute path (default: same as controller)                                                                        |
+---------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| pythonpath    | A list of paths to prepend to the Python seach path, e.g. ["..", "/home/joe/mystuff"] (default: [])                                                                                                              |
+---------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| cpu_affinity  | The worker CPU affinity to set - a list of CPU IDs (integers), e.g. [0, 1] (default: unset) - currently only supported on Linux and Windows, `not on FreeBSD <https://github.com/giampaolo/psutil/issues/566>`__ |                           
+---------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| reactor       | Choose the type of Twisted reactor, instead of the one chosen automatically. See below.                                                                                                                          |

Selecting a **Twisted reactor** is platform-based: ``reactor`` takes a
dictionary as an argument, with the platform as the keys and a single
reactor per platform as the value.

Platform values which are handled are ``bsd`` (with possible prefixes),
``darwin``, ``win32`` and ``linux``, while reactor values are
``select``, ``poll``, ``epoll``, ``kqueue``, and ``iocp``.

Additionally, the **process environment** for the worker can be
determined using the option ``env`` - for more information see :doc:`Process Environments <Process-Environments>`
