[jira] [Created] (AIRFLOW-5880) Enforce unique task ids

Bas Harenslak created AIRFLOW-5880:
--------------------------------------

             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: [https://github.com/apache/airflow/commit/385add2bf3eb7cd6103cfec0e5516234eeb72443]
