Tableau OCF Connector: Version 1.9.2

Fixed Issues

Metadata Extraction Fails for Site ID Provided in Upper Case

While connecting to the Tableau cloud, if the Site ID provided in the Connector Settings section of the General Settings tab is not in lower case, then MDE fails for the Tableau OCF connector version 1.9.0 and higher.

Now, the connector ignores case sensitivity for Site ID and proceeds with MDE. (AL-159423)

Tableau OCF Connector: Version 1.9.0


With Alation version 2024.1.2 and Tableau OCF connector version 1.9.0, Alation has introduced an enhanced user interface for configuring the Tableau OCF data source settings.


The connector version is compatible with Alation versions prior to 2024.1.2. However, you will view the old user interface with Alation versions prior to 2024.1.2

The documentation for the new Tableau OCF experience is available at : Tableau OCF Connector Documentation.

The enhanced user interface provides the following features:

Better User Experience

The enhanced Tableau user interface provides better navigation and multiple visual cues, making it easy to configure and manage Tableau data source.

Easy to Connect

The Tableau user interface now provides a step-by-step process to connect to your Tableau data source easily and quickly.

Additional Error-Prevention Checks

The Tableau user interface now includes added checks to avoid obvious configuration mistakes. The user interface also includes text to assist and provide cues while configuring.

Detailed Error Reports and Troubleshooting Support

The improved Tableau user interface makes troubleshooting easier for metadata extraction and query log ingestion, as you can now have a detailed error report for both processes. The report contains a detailed error description and steps to resolve the issue. (AL-139399)

Improved NODE_LIMIT_EXCEEDED Error Handling

The improved Tableau OCF connector reduces the possibility of encountering the NODE_LIMIT_EXCEEDED error.


If you continue to encounter the NODE_LIMIT_EXCEEDED error, Alation recommends that you increase the Node limit on Tableau.
