--------------------------------------
Summary: Enforce unique task ids
Key: AIRFLOW-5880
URL: https://issues.apache.org/jira/browse/AIRFLOW-5880
Project: Apache Airflow
Issue Type: Improvement
Components: core
Affects Versions: 2.0.0
Reporter: Bas Harenslak
Currently, task with equal ids in a DAG simply overwrite each other and the
last assigned task is saved. This can lead to unexpected behaviour and an
exception should be raised.
We've had a PendingDeprecationWarning on this for 4 years, time to get rid of
it:
