D1 is still pretty limited in my experience. No read replicas really kills any of the meaningful benefit of the architecture, and being built off of a (mostly) SQLite-compliant API makes me nervous as it isn't really SQLite at all.

Last year's major Cloudflare outage really was the final straw for me with regards to D1. I don't mean that as a knock at Cloudflare at all, the situation sounded horrible and I appreciate how the entire team responded to it. I just worry that internal responses to fundamental infrastructure issues will leave newer projects like D1 on ice for a year or two.

D1 (the ability to query your database at the edge) didn't get knocked offline during that outage though?

We did actually run into D1 issues during the outage, though I don't remember exact details on what was down. Our issues may have been API related with reads still functional.

My concerns, and this is very much my own concerns with no context of what has or is happening internally st Cloudflare, is that the outage exposed some serious issues that will take time to fix safely. The fact that D1 still doesn't support replication is an indication to me that it has been deprioritized, likely with other newer and less used products, while the infrastructure updates are dealt with.

There’s no way of knowing from the outside, but nothing in the April 1 announcement for D1 suggests deprioritization to me. They just announced that they’re doing read replication, describing how it will work in detail. Why preannounce it if they’re not working on it?

My guess is that they wanted it for 1.0 but the release slipped. It happens.

D1 is definitely not deprioritized. We're heads down on replication, and it's important for us to get it right. Takes time!
