@tomchristie databases looks awesome! I could see it's in alpha yet, but out of curiosity: are you using it already to prototype some future service? I'll give it a shot tomorrow probably 😉

[tomchristie]

I have something that I'll start using it with, yes.

Tho I'm pretty focused on building out more OSS tooling, rather than service-building right now. It's feasible that next up will be "and here's a fully-fledged ORM that sits on top of databases", but let's not get too far ahead of ourselves. 😝

@tomchristie hahaha yeah, that makes sense. SQLAlchemy is there now for more than 10 years and is rock solid enough to trust on it with eyes blindfolded. I think that if the necessity really grows, SQLAlchemy might end up with an async implementation by itself - we already have GINO and if my memory does not betrays me, @zzzeek once wrote in his blog (regarding the arrival of asyncio and etc) that the required changes in SQLAlchemy are actually "doable" to achieve that (section "SQLAlchemy? Asyncio? Yes?") - but he's the author, I think that thought must be deep buried in his mind ... But I'm eager to see more async stuff coming out of (or for) SQLAlchemy 😅
