fixes:
|
|
- |
|
|
Used "passive_deletes=True" in the configuration of relationships in
|
|
SQLAlchemy models. This improves deletion of graphs of related objects
|
|
stored in DB because dependent objects don't get loaded prior to
|
|
deletion which also reduces the memory requirement on the system.
|
|
