What are the best practices for seeders after migration?

[yusuke2930]

I want to insert master data which is seed data after migration.
Where would you like to implement this?
init_db.py?

init_db function from backend/app/core/db.py serves this specific purpose.
In default configuration. it's run by prestart service right after applying migrations (see backend/scripts/prestart.sh)
