> 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
> Priority: Major
> Labels: performance
>
> 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.
