You can now view the connection metadata on Alation for data sources based on Excel sheet embedded from Onedrive. (AL-165743)
Fixed Issues¶
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.
