Refreshing Source Data from Cloud Storage Locations

You can refresh source data stored in a cloud storage location or database, such as AWS S3 or Snowflake, to make the latest data available in mastering flows.

Important: Refreshing source data updates that data in all data products in which it is used.

If your source dataset’s schema has changed since importing it into Tamr Cloud, then your refresh will fail. For example, if you have new, removed, or renamed columns in your source dataset’s schema, your refresh will fail. Instead of refreshing, reimport your source dataset in Admin > Sources.

To upload a newer version of your existing source data:

Navigate to Menu > Sources.
To refresh a source, select Refresh in the source row.

Reuploading a Source File

The Refresh option is not available for uploaded source files. If your source dataset’s schema has changed since uploading it into Tamr Cloud, then you’ll need to add the updated source as a new source dataset in Admin > Sources.

Note: If you need to maintain your Tamr IDs, delete the original source and then reupload the updated source with the same source name as the original.

Deleting a Source

Important: Deleting a source file removes it from Tamr Cloud. If you delete a source file used in data product mastering flows, that file will no longer be available to those data products.

To delete a source:

Navigate to Menu > Sources.
Locate the source you want to delete, and select Delete in its row.
Confirm the deletion.
