Right, I get that usecase. You have to crunch numbers that sit somewhere, and store the outputs in the same place. DuckLake is great for that. But where does this DuckDB client-server setup fit in?

I can't think of many use cases for this and Arrow Flight, other than moving data around.

That's very cool, thanks for sharing. Our of curiosity, did you ever get to run on a Twitter/X stream of political tweets?

You are correct. To be fair I wasn't focused on comparing the runtimes of both methods. I just wanted to give a baseline and show that the batch approach is more accurate.

Author here. Thank you very much for the comment. I will take a look. This is a great case of Cunningham's law!

Author here. Thanks for your comment!

Compression algorithms may have been supporting incremental compression for a while. But as some have pointed out, the point of the post is that it is practical and simple to have this available in Python's standard library. You could indeed do this in Bash, but then people don't do machine learning in Bash.

Ok that makes sense! On my side I can get away with using it through WASM. But your performance needs won't allow that.

I'm curious because I have a similar use case for a querying frontend. Did you consider using https://github.com/tobymao/sqlglot? If so, what was missing to justify writing your own parser?

Hello HN. 5 years ago I posted an article about text classification via data compression. I got helpful and educative comments in response. Now that Python have shipped zstd in 3.14, I thought it would be time to revisit this approach. The throughput figures are much better. This means you can do baseline machine learning with Python's standard library!

Op here. I tried what the font a bit but didn't mention it in the article. I didn't get good results with it. Although it's probably a good idea to ask it for a guess, and feed that to the LLM too.

New comment by Lemaxoxo in "Lea: Minimalist Alternative to Dbt"

Lemaxoxo — Tue, 17 Oct 2023 09:54:16 +0000

Cheers! Mainly a couple of things:

- I don't like to have to put {{ ref('source') }} everywhere. I think the tool should parse dependencies automatically. I wrote more about this here: https://maxhalford.github.io/blog/dbt-ref-rant/ - I don't like the idea each .sql file has to have an associated .yml file. It feels better to have everything in one place. For instance, with lea you can add a @UNIQUE tag as an SQL comment to unit test a column for uniqueness.

Moreover, although dbt brought a shift in the way we do data (which is great) it's very straightforward under the hood. It boils down to parsing queries, organizing them in a DAG, and processing said DAG. dbt feels bloated to me. Also, it seems to me some of the newer cool features are going to be put behind a paywall (e.g. metric layers)

Hey there HN. lea is a tool we developed over the past year at Carbonfact. Carbonfact is a platform that helps fashion brands decarbonize. We believe in doing this in a data-driven way, and lea is a cornerstone for us.

Hey, great work. Do you think this algorithm would be amenable to be done online? I'm the author of River (https://riverml.xyz) where we're looking for good online clustering algorithms.
