Deleting a Dataset from All Projects

Admins can delete a dataset, which removes it from all projects.

When you delete a dataset using the dataset catalog, Tamr Core removes it from all projects. To remove a dataset from a project without deleting it from the system, see Removing a Dataset from a Project.

Before You Begin:

Before you delete a dataset, be sure to:

  • Back up your Tamr Core instance.
  • Remove the dataset from all projects in which it is an input dataset.
  • Update the unified datasets of all projects in which it was an input dataset.
  • Delete the sample dataset that resulted from profiling the dataset.
  • Remove the dataset from any projects or datasets that depend on it.
    Tip: the Tamr Toolbox includes a utility that gets a list of datasets and projects downstream from a specified dataset.

If the dataset you want to delete is a derived dataset for a project that has been deleted, a system administrator can use the Dataset Cleanup utility to find and convert these to source datasets for deletion.

Note: Deleting a unified dataset submits a job that can be resource-intensive to run. To monitor the progress of the job see Monitoring Job Status.

To delete a dataset from all projects:

  1. At the top right of your browser, select Dataset Catalog. A list of all datasets appears.
  2. Locate the dataset and select the checkbox that appears as you move your cursor over the left end of its row.
  3. Select Delete. A message indicates whether it is possible to delete the dataset or if any preliminary action is required. To delete the dataset, select Delete.
