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…

Actually δx is faster than the "duckdb embedded in postgres" options: https://benchmark.clickhouse.com/#system=+_etx|_b|_i )|dula|pnc&type=-&machine=-6t|ca2|6ax|g4e|6ale|3al&cluste…

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 thi…

> - Is ~300x faster than Postgres on analytical workloads. Right now it's 2x slower than Clickhouse on clickbench and I think it's possible to get faster than Clickhouse That sound…

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 sou…

A bit of a shameless plug, but I've been working on this for a few months in the form of an extension: https://github.com/xataio/deltax When I started I thought there's too much in…

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 p…

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. Thi…

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. - Automati…

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-... …

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 c…

> The Amp editor extensions will self-destruct on March 5 at 8pm Pacific Time. Time to switch to the Amp CLI. That's an interesting way to tackle the removal of features.

> The Postgres extension model to capture the metrics (we also experimented with eBPF, but it causes too many kernel-user space context switches when you can do the same in an exte…

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 poo…

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 a…
