Non-blocking ORM for Tornado?

Question

Is there any asynchronous Python ORM other than Twistar ?

I'm looking for lightweight ORM for non-blocking API, built on top of tornado. Of course, I can write raw SQL queries using momoko, but I'd like to work with objects.

Answer 1

Sure, it is! Look at peewee and peewee-async extension. Disclaimer: extension is only for PostgreSQL at the moment and I'm an author of extension :)

It's not specifically for Tornado, but Tornado can run on asyncio event loop.

Answer 2

It's been 5 years, and a lot changed. We wrote GINO to be a lightweight ORM on top of asyncpg and SQLAlchemy core . It is for asyncio and PostgreSQL only. GINO as "GINO Is Not ORM", because it applied almost none usual ORM patterns, in order to be explicit and simple.

Answer 3

None exist. The only ORM that could even consider coming close to being lightweight is PeeWee , and that isn't async. ORMs are hard to write, and even harder to write well . It needs to have a nice, clean API, expose many features of the underlying DB, and be efficient. A tall order!

There aren't many ORMs for Python, and even fewer async ones. Sorry.

Answer 4

Have a look at Tortoise ORM

Its aiming to be a full-featured ORM inspired by Django syntax , but asycnio only. Since Tornado 5.0 runs on asyncio, it should just work.

Answer 5

If using mongo you can look into Asyncmongo (not an orm but let's you access your data Async) https://github.com/bitly/asyncmongo

if it is of interest see video and slides from this webminar: "Asynchronous MongoDB with Python and Tornado" http://www.10gen.com/presentations/webinar/Asynchronous-MongoDB-with-Python-and-Tornado

Answer 6

你可能想看看Monguo ，一个“全功能，异步MongoDB ORM与Tornado应用程序的电机驱动程序”，因为它描述了自己。

Answer 7

You may want to have a look at umysqldb( https://github.com/hongqn/umysqldb ), A MySQLdb compatible wrapper around ultramysql. ultramysql compatible with gevent through monkey patching.
