 ## Error handling
 
-If `around` or `next` methods throw an error, the error will show up in logs and it'll trigger the Incremental Entity Provider to try again after a backoff period. It'll keep trying until it reaches the last backoff attempt. You don't need to do anything special to handle the retry logic.
+If `around` or `next` methods throw an error, the error will show up in logs and it'll trigger the Incremental Entity Provider to try again after a backoff period. It'll keep trying until it reaches the last backoff attempt, at which point it will cancel the current ingestion and start over. You don't need to do anything special to handle the retry logic.
