# Purge State Information

NiFi Ingest Connectors keep a record of the items they have retrieved. If you modify the configuration of a connector, you might want to delete the state information so that the connector ingests all of the items again.

To delete the state information that has been saved by a NiFi Ingest connector, use the following procedure.

To delete state information saved by a connector

1. Open the Apache NiFi user interface in your web browser.

2. Right-click the connector processor and click Configure.

   The Configure Processor dialog box opens.

3. Click the Properties tab.

4. Click Advanced.

   The advanced configuration page opens.

5. Click Purge Datastore.

   The state information is deleted.
