    There are 25 graph databases all going me too in the AI/LLM driven cycle.

    Writing it in Rust gets visibility because of the popularity of the language on HN.

    Here's why we are not doing it for LadybugDB.

    Would love to explore a more gradual/incremental path.

    Also focusing on just one query language: strongly typed cypher.

    Serious question: are there any actually good and useful graph databases that people would trust in production at reasonable scale and are available as a vendor or as open source? eg. not Meta's TAO

      Serious answer: limiting to just Open Source: JanusGraph, DGraph, Apache AGE, HugeGraph, MemGraph and ArcadeDB all meet that criteria.

      Yeah: Postgres, etc.

      When you actually need to run graph algorithms against your relational data, you export the subset of that data into something like Grafeo (embedded mode is a big plus here) and run your analysis.

    Does anyone have any experience with this DB? Or context about where it came from?

    From the commit history it's obvious that this is an AI coded project. It was started a few months ago, 99% of commits are from 1 contributor, and that 1 contributor has some times committed 100,000 lines of code per week. (EDIT: 200,000 lines of code in the first week)

    I'm not anti-LLM, but I've done enough AI coding to know that one person submitting 100,000 lines of code a week is not doing deep thought and review on the AI output. I also know from experience that letting AI code the majority of a complex project leads to something very fragile, overly complicated, and not well thought out. I've been burned enough times by investigating projects that turned out to be AI slop with polished landing pages. In some cases the claimed benchmarks were improperly run or just hallucinated by the AI.

    So is anyone actually using this? Or is this someone's personal experiment in building a resume portfolio project by letting AI run against a problem for a few months?

      That is a lot of code for what appears to be a vanilla graph database with a conventional architecture. The thing I would be cautious about is that graph database engines in particular are known for hiding many sharp edges without a lot of subtle and sophisticated design. It isn't obvious that the necessary level of attention to detail has been paid here.

        Are you talking about Andy Pavlo bet here?

        https://news.ycombinator.com/item?id=29737326

        Kuzu folks took some of these discussions and implemented them. SIP, ASP joins, factorized joins and WCOJ.

        Internally it's structured very similar to DuckDB, except for the differences noted above.

        DuckDB 1.5 implemented sideways information passing (SIP). And LadybugDB is bringing in support for DuckDB node tables.

        So the idea that graph databases have shaky internals stems primarily from pre 2021 incumbents.

        4 more years to go to 2030!

        • jandrewrogers 1 hour ago
          I wasn't referring to the Pavlo bet but I would make the same one! Poor algorithm and architecture scalability is a serious bottleneck. I was part of a research program working on the fundamental computer science of high-scale graph databases ~15 years ago. Even back then we could show that the architectures you mention couldn't scale even in theory. Just about everyone has been re-hashing the same basic design for decades.

          As I like to point out, for two decades DARPA has offered to pay many millions of dollars to anyone who can demonstrate a graph database that can handle a sparse trillion-edge graph. That data model easily fits on a single machine. No one has been able to claim the money.

          Inexplicably, major advances in this area 15-20 years ago under the auspices of government programs never bled into the academic literature even though it materially improved the situation. (This case is the best example I've seen of obviously valuable advanced research that became lost for mundane reasons, which is pretty wild if you think about it.)

          > There are some additional optimizations that are specific to graphs that a relational DBMS needs to incorporate: [...]

          This is essentially what Kuzu implemented and DuckDB tried to implement (DuckPGQ), without touching relational storage.

          The jury is out on which one is a better approach.

      • justonceokay 2 hours ago
        Yes a graph database will happily lead you down a n^3 (or worse!) path when trying to query for a single relation if you are not wise about your indexes, etc.
        • cluckindan 54 minutes ago
          That sounds like a ”graph” DB which implements edges as separate tables, like building a graph in a standard SQL RDB.

          If you wish to avoid that particular caveat, look for a graph DB which materializes edges within vertices/nodes. The obvious caveat there is that the edges are not normalized, which may or may not be an issue for your particulat application.

        • adsharma 2 hours ago
          Are you talking about the query plan for scanning the rel table? Kuzu used a hash index and a join.

          Trying to make it optional.

          Try

          explain match (a)-[b]->(c) return a.rowid, b.rowid, c.rowid;

      Using a LLM coded database sounds like hell considering even major databases can have some rough edges and be painful to use.
    • arthurjean 1 hour ago
      Sounds about right for someone who ships fast and iterates. 54 days for a v0 that probably needs refactoring isn't that crazy if the dev has a real DB background. We've all seen open source projects drag on for 3 years without shipping anything, that's not necessarily better
    • gdotv 2 hours ago
      Agreed, there's been a literal explosion in the last 3 months of new graph databases coded from scratch, clearly largely LLM assisted. I'm having to keep track of the industry quite a bit to decide what to add support for on https://gdotv.com and frankly these days it's getting tedious.

    Overwhelmed by the sheer number of graph databases? I released a new site this week that lists and categorises them. https://gdb-engines.com
  • satvikpendem 3 hours ago
    There seem to be a lot of these, how does it compare to Helix DB for example? Also, why would you ever want to query a database with GraphQL, for which it was explicitly not made for that purpose?

    The d:Document syntax looks so happy!

    Interesting... Need to check how this differs from agdb, with which I had some success for a sideproject in the past.

    https://github.com/agnesoft/agdb

    Ah, yeah, a different query language.

    I was ready to learn more about this but I saw "written in Rust" and I literally rolled my eyes and said never mind.
    • chuckadams 17 minutes ago
      Too bad you don't do the same for commenting on HN.
    • ComputerGuru 53 minutes ago
      I think "written by genAI" should be a bigger turnoff than "written in Rust".
      • andriy_koval 27 minutes ago
        alternative opinion:

        * it is possible to write high quality software using GenAI

        * not using GenAI could mean project won't be competitive in current landscape

        • quantumHazer 9 minutes ago
          > not using GenAI could mean project won't be competitive in current landscape

          why? this is false in my opinion, iterating fast is not a good indicator of quality nor competitiveness

    This looks like another avant-garde "art" project.
