You can do without a database backend but of course then the task logs are not kept in case of restart. Currently you can use any SQL database that SQLAlchemy supports, MongoDB or CSV files, or any other if you wish to extend Red Bird. It uses Red Bird (another project of mine) to abstract the data store: https://red-bird.readthedocs.io/en/latest/. And it just extends the logging library for reading task logs.
It seems I did not yet implement the set_repo method even though the docs talk about this but here's one way to set a CSV repo, for example: https://github.com/Miksus/rocketry/issues/108#issuecomment-1...
