Summary: Introduce run_type in DAG Run table
Key: AIRFLOW-6242
URL: https://issues.apache.org/jira/browse/AIRFLOW-6242
Project: Apache Airflow
Issue Type: Bug
Components: backfill, scheduler
Affects Versions: 1.10.6
Reporter: Kamil Bregula
Hello,
Before you start reading this ticket, I want to tell you one thing - you are
wonderful.
We use queries that use like expressions to filter two types of DAG Run.
* Backfill:
[https://github.com/apache/airflow/blob/699aea8ee368abcba29d717daf2580f897ab9d93/airflow/jobs/backfill_job.py#L52]
* Scheduled
[https://github.com/apache/airflow/blob/699aea8ee368abcba29d717daf2580f897ab9d93/airflow/models/dagrun.py#L46]
This type of expression can affect performance and it seems a better idea to
store this information in a separate column. This may allow a query planner to
create a better query plan in the database engine.
Thanks for reading this ticket.
