Microsoft Azure Cosmos
====================================

The Microsoft Azure Cosmos connection type enables the Azure Cosmos Integrations.

Authenticating to Azure
-----------------------

There is one way to connect to Azure Cosmos using Airflow.

1. Use `Primary Keys
   <https://docs.microsoft.com/en-us/azure/cosmos-db/secure-access-to-data#primary-keys>`_
   i.e. add specific credentials (client_id, secret, tenant) and account name to the Airflow connection.

Default Connection IDs
----------------------

All hooks and operators related to Microsoft Azure Cosmos use ``azure_cosmos_default`` by default.

Configuring the Connection
--------------------------

Login
    Specify the Cosmos Endpoint URI used for the initial connection.

Password
    Specify the Cosmos Master Key Token used for the initial connection.

Extra (optional)
    Specify the extra parameters (as json dictionary) that can be used in Azure Cosmos connection.
    The following parameters are all optional:

    * ``database_name``: Specify the azure cosmos database to use.
    * ``collection_name``: Specify the azure cosmos collection to use.

When specifying the connection in environment variable you should specify
it using URI syntax.

Note that all components of the URI should be URL-encoded.

For example:

.. code-block:: bash

   export AIRFLOW_CONN_AZURE_COSMOS_DEFAULT='azure-cosmos://https%3A%2F%2Fairflow.azure.com:master%20key@?database_name=mydatabase&collection_name=mycollection'
