Daniel Imberman closed AIRFLOW-18.
----------------------------------
Resolution: Auto Closed
> Alembic's constraints and indexes are unnamed thus hard to drop or change
> -------------------------------------------------------------------------
>
> Key: AIRFLOW-18
> URL: https://issues.apache.org/jira/browse/AIRFLOW-18
> Project: Apache Airflow
> Issue Type: Improvement
> Components: database
> Reporter: Bolke de Bruin
> Assignee: zgl
> Priority: Critical
> Labels: database
>
> Eg. in XXX_add_dagrun.py the constraint is added without a name:
> sa.UniqueConstraint('dag_id', 'execution_date'),
> This makes constraint naming database specific, ie. postgres' name for the
> constraint be different than mysql's and sqllite's.
> Best practice per http://alembic.readthedocs.io/en/latest/naming.html is to
> have naming conventions that are being applied.
