November 20, 2024¶
Tableau OCF Connector: Version 1.12.4¶
Fixed Issues¶
Temporary Objects Displayed in Lineage for Google BigQuery¶

October 30, 2024¶
Tableau OCF Connector: Version 1.12.3¶
Enhancements¶
Improved User Experience When Handling Data Source Connection and Lineage Data¶
The Tableau OCF connector now enables you to view table or query information related to published or unpublished/embedded data sources when this information is available as part of Tableau metadata API, even when host or port information is unavailable.
In such cases, users can view lineage by linking the BI, RDBMS, or EDW data source cataloged in Alation using the Lineage Settings tab on the Tableau OCF connector Settings page. (AL-170414)
Note
Rerun lineage computation or MDE after linking the data sources.
Improved Error Handling in Tableau Metadata API Response¶
The connector will now include the request ID in the Tableau metadata API error message for the following invalid response from Tableau metadata API:
The field at path ‘/publishedDatasourcesConnection/nodes[285]/site’ was declared as a non null type, but the code involved in retrieving data has wrongly returned a null value. The graphql specification requires that the parent field be set to null, or if that is non nullable that it bubble up null to its parent and so on. The non-nullable type is ‘TableauSite’ within parent type ‘PublishedDatasource’. Parameters -> first 1000, after cursor: null. There might be missing metadata for Published Datasources.
You can use the request ID to contact the Tableau Support team to resolve this issue. (AL-176692)

Project Deletion During Metadata Extraction¶
Projects get deleted from Alation during metadata extraction as Tableau fails to return the metadata due to the Tableau metadata API timeout issue. For more information on this issue, see Help Center Page.
The connector now handles the timeout errors in the Tableau Metadata API to reduce the impact and prevent deletion of the cataloged metadata.
The connector now captures the timeout issue as part of the error report (available for download in the Job Details). (AL-164024)
Important
This change will not restore the objects that may have been removed due to a timeout error in the Tableau Metadata API prior to upgrading to this version.
