Hopefully, we'll soon have Iceberg Materialized Views: github.com/apache/icebe...
They would be the perfect destination for the push queries.

That's awesome. I didn't know that.

I always think about the Iceberg metadata as a 2 level tree based multidimensional spatial index. The way you construct the tree is up to you.
It's just that Iceberg was designed for really huge tables and they decided to split the metadata over multiple files.

I find the Datawarehouse Toolkit and Designing Data-Intensive Applications both incredibly good.
There will be a second edition of DDIA soon!

Too bad, doesn't look like there will be an online recording.
I'd love to hear your take on columnar formats for AI and if we can evolve parquet accordingly.

Regarding the battery life, do you have some kind of CPU scaling installed?
One bad thing about arch Linux is that it comes with almost no defaults installed.
I installed power-profiles-deamon and it helped a lot with the battery.

Yeah classic, I should also do a service sometime. But probably something also has to happen first ;)

It's a really difficult question, because in the end you need to pay developers to build the software.
I just feel that many of those companies get really greedy and want to raise a lot of money. And once you raised a lot you are forced to bring in bigger returns that aren't possible with OSS.

I think at some point you will need columnar storage to store the list of all table formats.

Uff, that's rough. Did you have the stuff to fix it? Or did you have to do the walk of shame?

Same here. The design is so awesome.
Also love the "Unix" style interaction which makes it compose so well with other tools.

I tried Aider and Claude Code, their approaches are very similar but Claude Code feels much more powerful. It's really great at getting additional context in the process. While Aider only gets it beforehand.
The only thing that's missing from Claude Code is AI comments: aider.chat/docs/usage/w...

Awesome post, as always!
One thing I realized lately is that the authentication should be standardized with the Iceberg REST catalog (like an OIDC endpoint).
Otherwise every vendor has their own authentication and only their client will know how to authenticate.
