Installation & Configuration
============================

Getting Started
---------------

Panoramix is currently only tested using Python 2.7.*. Python 3 support is
on the roadmap, Python 2.6 won't be supported.

Follow these few simple steps to install Panoramix.::

    # Install panoramix
    pip install panoramix

    # Create an admin user
    fabmanager create-admin --app panoramix

    # Initialize the database
    panoramix db upgrade

    # Create default roles and permissions
    panoramix init

    # Load some data to play with
    panoramix load_examples

    # Start the development web server
    panoramix runserver -d


After installation, you should be able to point your browser to the right
hostname:port [http://localhost:8088](http://localhost:8088), login using
the credential you entered while creating the admin account, and navigate to
`Menu -> Admin -> Refresh Metadata`. This action should bring in all of
your datasources for Panoramix to be aware of, and they should show up in
`Menu -> Datasources`, from where you can start playing with your data!


Configuration
-------------

To configure your application, you need to create a file (module)
``panoramix_config.py`` and make sure it is in your PYTHONPATH. Here are some
of the parameters you can copy / paste in that configuration module: ::

    #---------------------------------------------------------
    # Panoramix specifix config
    #---------------------------------------------------------
    ROW_LIMIT = 5000
    WEBSERVER_THREADS = 8

    PANORAMIX_WEBSERVER_PORT = 8088
    #---------------------------------------------------------

    #---------------------------------------------------------
    # Flask App Builder configuration
    #---------------------------------------------------------
    # Your App secret key
    SECRET_KEY = '\2\1thisismyscretkey\1\2\e\y\y\h'

    # The SQLAlchemy connection string.
    SQLALCHEMY_DATABASE_URI = 'sqlite:////tmp/panoramix.db'

    # Flask-WTF flag for CSRF
    CSRF_ENABLED = True

    # Whether to run the web server in debug mode or not
    DEBUG = True

This file also allows you to define configuration parameters used by
Flask App Builder, the web framework used by Panoramix. Please consult
the `Flask App Builder Documentation
<http://flask-appbuilder.readthedocs.org/en/latest/config.html>`_
for more information on how to configure Panoramix.


Caching
-------

Panoramix uses `Flask-Cache <https://pythonhosted.org/Flask-Cache/>`_ for
caching purpose. Configuring your caching backend is as easy as providing
a ``CACHE_CONFIG``, constant in your ``panoramix_config.py`` that
complies with the Flask-Cache specifications.

Flask-Cache supports multiple caching backends (Redis, Memcache,
SimpleCache (in-memory), or the local filesystem).

For setting your timeouts, this is done in the Panoramix metadata and goes
up the "timeout searchpath", from your slice configuration, to your
data source's configuration, to your database's and ultimately falls back
into your global default defined in ``CACHE_CONFIG``.


Druid
-----

* From the UI, enter the information about your clusters in the
    ``Admin->Clusters`` menu by hitting the + sign.

* Once the Druid cluster connection information is entered, hit the
    ``Admin->Refresh Metadata`` menu item to populate

* Navigate to your datasources
