Summary: dag.sub_dag(...) speedups
Key: AIRFLOW-2777
URL: https://issues.apache.org/jira/browse/AIRFLOW-2777
Project: Apache Airflow
Issue Type: Improvement
Reporter: Abdul Nimeri
Assignee: Abdul Nimeri
dag.sub_dag(...) currently works by first deep copying the entire dag, and then
filtering down to the appropriate tasks. that can be slow since deep copying a
big dag takes a while. specifically, copying over all the tasks is the
bottleneck
this can be a lot faster by instead only copying over the filtered down tasks
