  • Bespoke query language creates lock-in and learning curve

    From 2 comments
    • > so much easier that it’s worth a bit of a learning curve I think you misspelled "vendor lock in"

    • This is very cool, and right up my alley. Hesitant to try it out because of the bespoke query language for now. I wonder if you'd like to share your thoughts on GQL becoming an…

  • Benchmark claims were not backed by published numbers

    From 2 comments
    • It sounds very intriguing indeed. However, the README makes some claims. Are there any benchmarks to support them? > Built for performance we're currently 1000x faster than…

    • how did you get it 3 OOMs faster than neo4j?

  • Name clashes with the Helix editor and an existing Helix database

    From 2 comments
    • Nice "I'll have this name" when there's already the helix editor :)
      lillecarl on HN
    • I don't think `helix-editor` is even on crates.io, just placeholders. https://github.com/helix-editor/helix/discussions/7038 That being said, when I saw `helix-db` I was thrown…

  • Embedded mode or browser WASM support

    From 2 comments
    • Congrats! Any chance Helixdb can be run in the browser too, maybe via WASM? I'm looking for a vector db that can be pre-populated on the server and then be searched on the client…

    • Can I run this as an embedded DB like sqlite? Can I sidestep the DSL? I want my LLMs to generate queries and using a new language is going to make that hard or expensive.

  • Python SDK with generated types

    From 1 comment
    • Looks very interesting, but I've seen these kind of multi-paradigm databases like Gel, Helix and Surreal and I'm not sure that any of them quite hit the graph spot. Does Helix…

Questions

  • How it compares to Kuzu, SurrealDB, ChromaDB, Memgraph and CozoDB

    From 4 comments
    • How does it compare with https://kuzudb.com/ ?
      esafak on HN
    • How does it compare to SurrealDB and ChromaDB?
      iamdanieljohns on HN
    • Very interesting project. Would be curious of a comparison with memgraph. Will definitely give it to try for my knowledge graph use case.
      ckugblenu on HN
    • Can you do a compare/contrast with CozoDB? https://github.com/cozodb/cozo

  • Whether it can run embedded like SQLite

  • Hardware and scaling requirements

    From 3 comments
    • I was thinking about intertwining Vector and Graph, because I have one specific usecase that required this combination. But I am not courageos or competent enough to build such a…

    • What would be a typical/recommended server setup for using this for RAG? Would you typically have a separate server for the GPUs and the DB itself?
      anonymousDan on HN
    • How scalable is your DB in your tests? Could it be performent on graphs with 1B/10B/100B connections?
