This thread seems to reflect how the HN audience has shifted — less commenters know what `ssh example.com` does and more commenters concerned about privacy policy.

To provide more context, our original plan was to launch the GA on March 22nd. However, we decided to move the date to April 15th because a few projects required additional time to…

Thank you, point taken. The blog post does mention memory limitations, but we could elaborate more on the fact that the index is entirely in-memory and clarify the user-visible con…

Yes, exploring http/3 is on the roadmap. One of the learnings for us was the fact that v8 is quite good with caching open TCP connection; For consecutive queries the same TCP+TLS s…

There is a second network interface attached to each pod and that interfaces are connected to vxlan-based overlay network. So during the migration VM can keep the same ip address (…

Main idea was one branch per pull request to better test migrations on a fresh data. But one branch per dev or branch per dev per pr will also work.

> The article ends with the statement that you are pretty much done here for now. Would optimizing your TLS termination not maybe offer some more ways to speed this up? Or is that …

Gotcha. I drew my conclusion based on the mentioned package.json. Now wonder why did you decide to go with rust for query engine? Do you compile it into wasm?

Another angle here is compatibility. With our current driver one can use ordinary node-postgres package, as we can substitute TCP-related calls with WebSocket calls during the buil…

Right, that is one of the use cases. Auth is tricky part in that setup -- in the browser user may change the query in arbitrary way. But there are some workarounds like obtaining J…

It is possible to create branch retroactively

And some other projects that DARPA worked on: https://spectrum.ieee.org/tech-history/space-age/the-bunny-t...

Licklider is one the main persons behind the ARPANET. The Imagineers of War by Sharon Weinberger has a lot of context on his time in DARPA. Few things that I found particularly not…

Postgres tracks maximal LSN among the evicted pages and passes it to the pageserver in the page request. If the pageserver hasn't received that LSN, it will wait for it to arrive.

Currently, we deploy three safekeepers, one in each AZ. We need to collect more stats on failure rates, and maybe we will go to 6 (3 AZs with two nodes in each) as Aurora does.

Right. Our design guideline is to get as much serverless behavior as possible while keeping full Postgres compatibility (in terms of features and expected performance). Single node…

Good catch! Currently, we don't, and we rely on k8s to stop the old node. Technically speaking, if k8s and our control plane are always good at stopping the old primary, we don't n…
