    I've been working on a graph database in Rust this year actually! I'd love to hear anything you can talk about wrt the query planner and/or how you decided to do cardinality estimation. I decided to go with an EAV graph which makes CE pretty complex, and it's been an interesting challenge to balance quality and speed and expressiveness in the query language

    congrats on the launch! site and docs look great.

    can you host this yourself or do you need to use helix-cloud? the chat thing on the side seems to push me to helix-cloud but it looks like that starts at like $600/mo which is above my experimentation budget.

    looking for a db for an agent memory application and i'd probably start with something that's just self-hosted / freeish. postgres is working ok but I want to start ingesting server and chat logs.

    We've been having some issues with intermittent performance on multi hop queries.

    What's your p99 like for multi hops?

    • GeorgeCurtis 7 hours ago
      In prod we see p99’s of <10ms ms for warm queries and around 50ms per hop for cold queries.

        Hmmm... I'll get in touch. Got an email i can reach out to, there doesn't seem to be one listed on your website?

        I'm more concerned about if the p99s stay consistent when things get spikey.

        dgraph is fine otherwise...

          Sure! You can email me personally at george@helix-db.com

      If your use case is OLAP based, please check it out PuppyGraph. It’s a graph query engine that sits on top of your Lakehouse (no ETL required). Our benchmark has shown consistently that 10-hop queries across billions of edges in <2 seconds. Our customers including some most data demanding companies like Coinbase, Datadog, Palo Alto Network, Netskope, AMD, etc.

        It's not, its actually our prod db with direct user usage - we self host a large dgraph cluster. We have a very large number of people manage their car and car histories with us and host a full replica of the UK MOT Database.

        We're fine with clickhouse and redshift for the OLAP work we do. I've been looking at ParaQuery lately if I really want to speed that up.

        • GeorgeCurtis 6 hours ago
          This sounds like a perfect usecase. Would love to learn more and see if we can help!

          email us: founders@helix-db.com

        PuppyGraph is a good fit for OLAP for sure.

        We’re just two young founders sharing what we’ve been building, so I’ll take the drive-by competitor plug as a compliment :)

        Definitely a different focus though. Helix is OLTP, built for operational graph + vector workloads, especially apps/agent memory where low-latency traversals and writes are concerned.

    Currently #5 on gdb-engines.com - definitely worth a look.

      How rankings are calculated? HelixDB has zero feature scores, unlike e.g. JanusGraph which is at #27 or Neo4j at #1.
      • cjlm 2 hours ago
        The feature scores are from a paper cited on the site. The ranking features are proprietary to dissuade gaming but are a blend of open public data across a number of different sources.

      yooo this is awesome. Didn't even realise :)

    Congrats on the launch George!

    Looking forward to looking into the generalised AI memory layer when it comes out.

  • caust1c 3 hours ago
    Where's the source code for the database itself? Looks like the repo is just a client.

    Congrats on the launch!

      This was a TEMPORARY decision we made, and I wrote a bit about why we did this here: https://x.com/georgecurtiss/status/2060043184059912470

      We’re 100% committed to going back to open-source on an Apache 2.0 license as soon as possible. In the meantime, you can continue to deploy us completely for free, however you like, using the compiled docker container.

    does it support fts/vector on edges of the graph?
    • GeorgeCurtis 7 hours ago
      Yes you can put vectors, full text data, secondary and range indexes on both nodes and edges.

    How does this compare vs. Turbopuffer?
    • GeorgeCurtis 7 hours ago
      We see comparable results for vectors and FTS.

      For vector search we have warm and cold p99s of approx 20ms and 400ms respectively. For FTS, warm and cold query p99s of approx 15ms and 250ms respectively.

      Both of these benchmarks were run on 1m docs.

    when will the graph memory layer be available?
  • raufakdemir 6 hours ago
    what language does this support? cypher/gremlin?
    • GeorgeCurtis 6 hours ago
      We don't support cypher or gremlin. We can

      You can query HelixDB using JSON or directly in your programming language of choice by using our Rust, TypeScript, Go or Python SDKs. We’ve found AI is very good at working with the SDKs and JSON itself to query, making the development experience much better than before: https://docs.helix-db.com/database/querying

    congrats! how does this compare to turbopuffer, surreal or other multi-model ones built on object storage or not
    • GeorgeCurtis 4 hours ago
      tpuffer is a vector/fts database. Surreal is a bit of an "everything database".

      We're a graph database with vector and FTS capabilities. Our vector and FTS benchmarks are comparable with tpuffer, but you would primarily use us for building whole applications, knowledge graphs, or AI memory/retrieval. Anything that is relationship intense.

      Let me know if this properly answers your question
