Snowflake Connection
====================

The Snowflake connection type enables integrations with Snowflake.

Authenticating to Snowflake
---------------------------

Authenticate to Snowflake using the `Snowflake python connector default authentication
<https://docs.snowflake.com/en/user-guide/python-connector-example.html#connecting-using-the-default-authenticator>`_.

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

Hooks, operators, and sensors related to Snowflake use ``snowflake_default`` by default.

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

Login
    Specify the snowflake username.

Password
    Specify the snowflake password. For public key authentication, the passphrase for the private key.

Host (optional)
    Specify the snowflake hostname.

Schema (optional)
    Specify the snowflake schema to be used.

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

    * ``account``: Snowflake account name.
    * ``database``: Snowflake database name.
    * ``region``: Warehouse region.
    * ``warehouse``: Snowflake warehouse name.
    * ``role``: Snowflake role.
    * ``authenticator``: To connect using OAuth set this parameter ``oath``.
    * ``private_key_file``: Specify the path to the private key file.
    * ``private_key_content``: Specify the content of the private key file.
    * ``session_parameters``: Specify `session level parameters <https://docs.snowflake.com/en/user-guide/python-connector-example.html#setting-session-parameters>`_.
    * ``insecure_mode``: Turn off OCSP certificate checks. For details, see: `How To: Turn Off OCSP Checking in Snowflake Client Drivers - Snowflake Community <https://community.snowflake.com/s/article/How-to-turn-off-OCSP-checking-in-Snowflake-client-drivers>`_.

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.

Example connection string:

.. code-block:: bash

   export AIRFLOW_CONN_SNOWFLAKE_DEFAULT='snowflake://user:password@snowflake.example/db-schema?account=account&database=snow-db&region=us-east&warehouse=snow-warehouse'
