Deleting a dataset
If you no longer need a dataset, you can delete it. Deleting a dataset doesn't affect the underlying data source in any way. It simply removes the information that DataBrew used to access the data source.
You can't delete a dataset if any other DataBrew resources rely on it. For example, if you currently have a DataBrew project that uses the dataset, delete the project first before you delete the dataset.
To delete a dataset, choose Dataset from the navigation pane. Choose the dataset that you want to delete, and then for Actions, choose Delete.
