Connectivity with Bridge
When data sources connect to on-premises data that Tableau Online can't reach directly, Tableau Bridge is used to facilitate connectivity.
Supported connection types
Bridge keeps data sources that connect to on-premises data up to date using the following connection types: extract and live.
When data sources use extract connections to connect to on-premises data, Bridge can be used to perform scheduled refreshes of the extracts. Refreshes can be scheduled for all data sources that connect to data listed in the Supported connectors section below. The type of data that Bridge can support falls into one of the following categories:
File data, including statistical files.
Private cloud data and some ODBC data, including Amazon Redshift, Teradata, and Snowflake.
Some web data connector (WDC) data if you access the data by entering a standard user name and password. Bridge can't be used to access a data provider's website using OAuth.
For additional requirements to support extract connections, see Additional requirements for extract connections.
Bridge can be used to support data sources that use live connections to on-premises data as well. Bridge supports data sources with live connections, using live queries, to most data sources listed in the Supported connectors section below. For example, Bridge supports maintaining live connections between your on-premises SQL Server or Oracle data.
For additional requirements to support live connections, see Additional requirements for live connections.
Unless otherwise specified, Bridge supports refreshes schedules (extract connection) and live queries (live connections) to on-premises data (accessible only from within a private network) whose data sources use the connectors in the table below.
Excel (extract refresh only)
Text File (extract refresh only)
Statistical File - .sas7bdat (extract refresh only)
Amazon Aurora for MySQL
Amazon EMR Hadoop Hive
Azure SQL Data Warehouse
Google Cloud SQL (extract refresh only)
HortonWorks Hadoop Hive
MAPR Hadoop Hive
Microsoft SQL Server
OData (extract refresh only)
Pivotal Greenplum Database
Progress OpenEdge (extract refresh only)
SAP HANA (extract refresh only)
SAP Sybase ASE
Tableau extracts (extract refresh only)
Web Data Connector (not using OAuth)
Other Databases (JDBC)
Other Databases (ODBC)
Limited connector support
Similar to Tableau, Bridge provides limited support for data sources that use the connector plugins, Web Data Connector, or a JDBC or ODBC driver to connect to an unsupported database. For more information about the support provided, see the following topics in the Tableau Help:
- Connector Plugin(Link opens in a new window)
- Web Data Connector(Link opens in a new window)
- Other Databases (JDBC)(Link opens in a new window)
- Other Databases (ODBC)(Link opens in a new window)
There are a few connectivity scenarios that Bridge does not support.
- Live connections to file-based data
- Extract connections or live connections to cube data
- Multi-connection data source (data sources that contain cross-database joins) when it uses one or more connectors not supported by Bridge. For more information, see Refreshing Cross-Database Joined Data Sources on Tableau Bridge(Link opens in a new window) in the Tableau Knowledge Base.
When to use an alternative to Bridge
Connecting to cloud data that Tableau Online can reach directly
For cloud data, setting up refresh schedules directly with Tableau Online is almost always a better (or in some cases the only) choice. For a list of connectors supported by Tableau Online, see Allow Direct Connections to Data Hosted on a Cloud Platform.
Note: For some WDC data sources, scheduling refreshes is not an option because of OAuth. For more information, see Working with data accessed through OAuth below.
Refreshing extracts of other cloud data
For some cloud data, you can sign in to by providing a standard user name and password. For example, you might be able to connect to a MySQL database hosted on a cloud platform. In a scenario like this, you can set up a refresh schedule for extracts that connect to this type of data directly with Tableau Online. For more information, see Schedule Refreshes on Tableau Online.
Data accessed through the provider’s web authorization page (OAuth) is not supported by Bridge. Popular providers that use OAuth include Salesforce.com, Google, and WDC data sources created from QuickBooks Online, Facebook, Twitter, and other websites.
To determine whether your data requires OAuth, when you sign in to your cloud data through Tableau Desktop, if you are redirected to the data provider’s sign-in page, that provider most likely uses OAuth or similar standard and therefore Bridge can't be used.
As an alternative to Bridge, to refresh data that connects through OAuth:
For extracts of Salesforce and Google data, you can set up a schedule directly on Tableau Online.
For extracts of WDC data sources you created from Facebook, Twitter, or other website, you can refresh the extracts from Tableau Desktop, either by using the Refresh from Source option, or by republishing the data source.
