-------------------------------------
Summary: 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
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}
