Jarek Potiuk commented on AIRFLOW-3985: --------------------------------------- Closing following the discussion in [https://github.com/apache/airflow/pull/4810] > Adding linear DAG relationships with unary operator > --------------------------------------------------- > > Key: AIRFLOW-3985 > URL: https://issues.apache.org/jira/browse/AIRFLOW-3985 > Project: Apache Airflow > Issue Type: New Feature > Reporter: Jarek Potiuk > Priority: Major > > It would be nice for development and testing to be able to build linear DAG > dependencies with unary + operator rather than with << with automated > upstream dependency to the previously added task. > Often during development we need to inject/remove tasks between two other > tasks and with unary operator it might be very easy to comment out whole > lines of code. > Example: > {code:java} > +op1 > +op2 > +op3{code} > might be equivalent to: > {code:java} > op1 >> op2 >> op3{code} > This way we can comment out one line: > {code:java} > +op1 > # +op2 > +op3{code} > equivalent to: > {code:java} > op1 >> op3{code} > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
