--------------------------------------
Summary: Avoid recreating task context
Key: AIRFLOW-4963
URL: https://issues.apache.org/jira/browse/AIRFLOW-4963
Project: Apache Airflow
Issue Type: Improvement
Components: core
Affects Versions: 1.10.5
Reporter: Bas Harenslak
The task context is created by taskinstance.get_template_context() and called
twice via _run_raw_task:
# context = self.get_template_context()
# 2nd time in render_template(), instead of passing it to render_template()
This is costly (lots of variables initialized, DB session, datetime
calculations) and can be avoided.
