Developing good ORMs is HARD!

Nickolas Grigoriadis https://2018.za.pycon.org/talks/24-de... As with many people, I was looking for an ORM for `asyncio` Python. Whilst `asyncio` is a great framework for I/O bound applications, there isn't any mature, recommendable ORMs for it. Many attempts to wrap an existing sync Python ORM (such as peewee or sqlAlchemy) by having them run in a separate thread, and then dealing with synchronising between the event loop and threads got abandoned, due to a myriad of problems, including performance, correctness and blocking. Other ORMs were abandoned before they worked, or had so many layers of abstraction that I feared to touch it. Then I came across [Tortoise ORM](http://tortoise-orm.readthedocs.io/) It had a simple design. (Inspired by the Django ORM syntax) It actually worked when I tried it out. So I decided to jump in, and help with development. In this talk I'll talk about my experience of being on a development team on an ORM. There is a reason there are so few successful ORM projects out there. Developing good ORMs are *HARD* pyconza2018 python
