We are seeing more and more specialized query engines. This is a query engine specialized for training pipelines. It is not general purpose - it is for providing batches of training data at workers. It uses Ray for parallelization. The kind of queries you need are random reads (to implement shuffling across epochs), arrow support (zero copy to Pandas DataFrames), and efficient checkpointing.

    Data operations are increasingly happening near the GPU side to boost efficiency—especially for compute-heavy workflows. Talking about Arrow file processing and zero-copy queries on DataFrames, which are becoming crucial for modern data pipelines. I think another option worth considering is chdb, which supports these features and fits well with this shift. (author of chdb here)

DuckDB itself is cool enough, especially when combined with SQLite and/or PostgreSQL, and now this. Thanks DeepSeek!

  • dcreater 6 hours ago

    How is duckdb combined with SQLite? Aren't they alternatives to each other?

    • jitl 4 hours ago

      Not sure what the poster meant but DuckDB is an analytics DB, it doesn’t have a btree index - at least not last time I looked. You could consider it the OLAP embedded DB to SQLite’s OLTP embedded db.

      DuckDB can read SQLite so you can even imagine using them side by side in the same system, serving point reads and writes from SQLite and using DuckDB for stuff like aggregates and searches that SQLite is slower at.

Confused by the example in the repo? What is the use case for this? Is it a replacement for dask, ray etc? (Not a professional swe)

If you want to checkout duckdb try QStudio. It's a free sql client with duckdb integrated: https://www.timestored.com/qstudio/help/duckdb-sql-editor. Disclaimer: I'm the main author.

      There are many themes to choose from. I recorded the demo on that page and I like windows 95. I concede it may not be pretty but I've always found it functional. The default is darcula theme like shown on the main page: https://www.timestored.com/qstudio/

Is the code written by the deepseek model?

I should probably give up on being a software engineer if it is.

  • cavisne 17 hours ago

    There is a chinese blogpost from 2019 about 3FS so it predates deepseek [1]. It will be interesting to see the benchmarks but I suspect without 3FS smallpond is not that useful (the bottleneck would move to the networked file system).

    None of the big US clouds support Infiniband broadly (Azure & Oracle have some support) so 3FS itself is not very useful to US companies who want to use public clouds.

      Not OP, but, anything that actually physically affects the real world for the better? For instance, large infrastructure engineering and construction projects are not going to run themselves any time soon. The world doesn't revolve around ad and fin tech.

      you can already google the information , the majority of a doctor's value is not in their information but their people and technical skills.

      • agilob 5 hours ago

        >the majority of a doctor's value is not in their information but their people and technical skills.

        Not even that, in the last years I haven't met a single doctor who would even care. Their value is now a necessary evil, they have the legal powers to recommend you to a hospital and give prescriptions. These legal powers will be much harder to change.

      • rscho 17 hours ago

        Well, googling the info is one thing. But today, medicine is still mostly a know-how profession. Residency is there mostly to transmit know-how.

    • nurettin 9 hours ago

      If your white collar job consists of simply using software, like copying numbers you see to an excel sheet, maybe. Otherwise they are pretty safe. People have been building tools and automation for thousands of years, yet nobody invented a fully automated cook for your fancy family dinner.

    • rscho 18 hours ago

      Yes, doctors are safe. Because they do things. With their hands. That no one else does.

      • aragonite 17 hours ago

        > Because they do things. With their hands. That no one else does

        That's only true of surgeons :) What if your specialty is nonsurgical (internal medicine, pediatrics, psychiatry, etc)?

        • rscho 17 hours ago

          Almost all specialties do various technical procedures that only them really know how to do. The extreme is psychoanalytic psychiatry, which are the only ones really doing nothing with their hands (yes, interventional psychiatry is a thing...). Now, you could argue that 'yes, but most of the times it's done by techs/nurses'. Well, no. When things go south, and in all places where there is noone else to do the stuff (of which there are many) docs are on their own.

          Regarding surgery, I expect it to be one of the easiest procedures to automate, actually (still quite hard, obviously). Because surgery is the only case where there's always advanced imaging available beforehand, and the environment is relatively fixed (OR).

          • menaerus 3 hours ago

            Why do you think medical science wrt complexity is any different than applied math, which computer science essentially is? People already can use LLMs to assist them in diagnosing health issues so why would it be hard to believe that the doctors won't be using the same kind of assistance soon too?

        • downrightmike 17 hours ago

          Not even true of all surgeons, the ones that make the most money use machines to work on things their hands couldn't do

          Is it really true that people drank bleach!? It always felt to me as some idiot did it once and it was repeated by the media endlessly, probably for clicks because this story is so dumb. Nonetheless the actual thing which people take is ClO2.

      • delfinom 17 hours ago

        Nope.

        Healthcare megacorps are buying up independent practices like crazy. All because doctors can't keep up with the bullshit IT required for insurance, state mandates, etc and that's in addition to the insanity of even renting commercial real estate for an office these days.

        These megacorps set quotas and push doctors to nickel and dime like crazy. They sure as shit will spend the money to find robots that can give you a prostate exam with a robot dildo.

        • mdaniel 17 hours ago

          Sounds good; if all these pro-AI folks could get it to complete the insurance paperwork that'd be swell. Actually, come to think of it, do that for the paperwork from both sides, doctor and patient, and eliminate and entire class of leaches upon humanity

          I'm going to laugh if DOGE eliminates the IRS, but also might be thankful

            We build software that automates insurance billing for clinics.

            And yes, the sentiment is correct that the burden of insurance encourages consolidation in healthcare. Wrapping that away (i.e. Stripe for healthcare financial infra) lowers the barrier to entrepreneurship.

          • rscho 17 hours ago

            Don't laugh too quickly, because what you describe is already happening: models are used to design processes allowing insurance corps to deny claims optimally, while on the other side models write your claims. If I were you, I wouldn't be laughing. If you are laughing, then you don't see where this is going to take us.

        • rscho 17 hours ago

          Except the tech to do that is not there, and we're quite far from it. It's one thing to have a robot write text, it's a whole other thing to have a robot perform at human level in medical procedures. Not happening tomorrow.

      • BobbyJo 17 hours ago

        People still write in languages that force you to manage your own memory.

        Once performance starts to matter (either due to scale or time requirements) abstractions always have tradeoffs you can't accept.

        • pyrolistical 16 hours ago

          So then, how can garbage collection ever be solved if it’s a trade-off

          • BobbyJo 15 hours ago

            And how can backends be abstracted away if there is a trade off?

            As long as compute is a meaningful percentage of spend, the trade off will matter.

            • pyrolistical 14 hours ago

              Right. So what does it look like for garbage collection to be solved? You’re saying it’s not ever possible

              • BobbyJo 13 hours ago

                I am saying it's not possible for the foreseeable future, yes. The same way backends becoming an abstraction most developers don't need to worry about is also not going to happen in the foreseeable future.
