This section describes new features to the Match transformation that you create in the Developer tool.
You can specify whether the transformation updates a current identity index data store with index data from a mapping data source. Use the Persistence Method option to set the update policy. Set a policy to update the data store with any index data from the data source that the data store does not contain. Alternatively, set a policy that does not update the data store with index data. By default, the transformation updates the data store.
