Can I change a DataLink schema without removing columns?

    Hi there!

    When going through the Datameer wizard, the schema will be rescanned at that time. If columns no longer exist in the source data, they will not be displayed in the wizard.

    However, there is a way to update a data link definition using the REST API. With this, you could export the current JSON settings, update the Accept Empty value for the desired column and then push the new JSON to a copy (or overwrite the original) Data link. Documentation for the REST API will contain the commands and syntax to use to read and write the Datalink definition.
