[jira] [Commented] (AIRFLOW-932) Backfills delete existing task instances and mark them as removed

    [ https://issues.apache.org/jira/browse/AIRFLOW-932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15890810#comment-15890810 ] 

Bolke de Bruin commented on AIRFLOW-932:
----------------------------------------

verify_integrity in models.py is where you would like to look at. As mentioned it sets a state to REMOVED if a task instance does not have a corresponding task in a DAG. It is there for auditing and versioning reasons. Does it affect running anything? A changed DAG cannot have a dependency on a non existent task.
