The Tableau connection type enables the Tableau Integrations.
Authenticating to Tableau¶
There are two ways to connect to Tableau using Airflow.
Use Password and Username Authentication i.e. add a
loginto the Airflow connection.
Use a Token Authentication i.e. add a
personal_access_tokento the Airflow connection (deprecated).
Authentication by personal token was deprecated as Tableau automatically invalidates opened personal token connection if one or more parallel connections with the same token are opened. So, in the environments with multiple parallel tasks this authentication method can lead to numerous bugs and all the jobs will not run as they intended. Therefore, personal token auth option is considered harmful until the logic of Tableau server client changes.
Only one authorization method can be used at a time. If you need to manage multiple credentials or keys then you should configure multiple connections.
Default Connection IDs¶
All hooks and operators related to Tableau use
tableau_default by default.
Configuring the Connection¶
- Login (optional)
Specify the tableau username used for the initial connection. Used with password authentication.
- Password (optional)
Specify the tableau password used for the initial connection. Used with password authentication.
Specify the Sever URL used for Tableau.
- Extra (optional)
Specify the extra parameters (as json dictionary) that can be used in Azure connection. The following parameters are all optional:
site_id: This corresponds to the contentUrl attribute in the Tableau REST API. The
site_idis the portion of the URL that follows the /site/ in the URL. For example, “MarketingTeam” is the
site_idin the following URL MyServer/#/site/MarketingTeam/projects. To specify the default site on Tableau Server, you can use an empty string '' (single quotes, no space). For Tableau Online, you must provide a value for the
site_id.This is used for both token and password Authentication.
token_name: The personal access token name. This is used with token authentication.
personal_access_token: The personal access token value. This is used with token authentication.
verify: Either a boolean, in which case it controls whether we verify the server’s TLS certificate, or a string, in which case it must be a path to a CA bundle to use. Defaults to True.
cert: if String, path to ssl client cert file (.pem). If Tuple, (‘cert’, ‘key’) pair.
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.
