I was hoping Zed will do a really good built-in diff editor with AI notes and comments, like https://github.com/modem-dev/hunk Perhaps this is going into this direction? I kind of like the Hunk workflow for reviews (of

Because you mentioned Xata (I'm the author of that blog post, thanks for mentioning it), this is pretty similar to what we do at the high level, but we built our own storage system rather than relying on Ceph. The reason is scalability

Yeah, spent a lot of time on parallelism, vectorizing, pipelining, filter push-downs, bloom filters, all the tricks out there. It's really fun to make pretty steady progress on this.

This is why I think sites like this one should show license information and make it simple to filter by OSS license. Otherwise it's the same trap, just one level deeper.

As small piece of feedback, I think it would be really good if the tools list would include license information, and make it easy to filter for open source tools/licenses. IMHO source-available extensions break part of what is attracti

For context, I'm CTO at Xata where we offer a Postgres service that differentiates via other ways (very fast CoW branching, scale-to-zero, anonymization, etc). We often recommend people keeping production where it is (RDS, Cloud SQL, o

I have been working on another PG extension for timeseries ( https://github.com/xataio/deltax ) for a few months, and trying to make it score as good as possible on ClickBench. This is a project that is simply lot of fun

Hi HN, This is Tudor from Xata. You can think of Xata as an open-source, self-hosted, alternative to Aurora/Neon. Highlight features are: - Fast copy-on-write branching. - Automatic scale-to-zero and wake-up on new connections. - 100%

It's funny that this news showed up just as we (Xata) have gone the other direction, citing also changes due to AI: https://xata.io/blog/open-source-postgres-branching-copy-on-... We did consider arguments in both

This sounds cool, adding to my list of things to try out. One note, this shouldn't be confused with https://github.com/xataio/pgstream which does logical replication/CDC with DDL changes.

Even then, though, it needs to run on the server so it's hard to guarantee to not impact performance and availability. There are many Postgres/Mysql proxies used for connection pooling and such, so at least we understand their imp

Others have mentioned similar solutions but I’d like to add one: a database solution with CoW branching and PII anonymisation solves the db part in a safe way. Disclaimer: I work at Xata.io, which provides these features. We have a recent b
