As someone who has been using alot of spacetime for side projects (like https://heat.echohack.app), I am continually impressed with the speed at which it operates.

I think there's alot of interesting things happening in the database space. Vitess/Neki, vector stores, spacetime are all really good things to be happening. I think it's a shame that database developers seem to have a drama filled timeline out there. It's... all very exciting, together.

Anyway, Some things that need improvement (some of which are addressed by this blog post):

1. Backups (fast recovery) and Disaster Recovery (slow, durable recovery)

This is a big one, but sometimes speed is not the only objective you have to meet. You need to have certainty that, if everything goes down that you (eventually) can bring things back online. I don't really have a way of doing that today.

2. Read replicas sure would be nice for analytic workloads

3. Durable writes to s3 would be nice for intermittent bursting workloads (like ci systems)

I think the Spacetime folks have their work cut out for them, not necessarily because of the technology (that's hard too) but because the AI models have seemingly decided that Neon and Postgres are all that exists.

I think spacetime has a bright future ahead of it, and I am wishing the team all the best as they work hard to imprint something new on the universe.
