GraphAr – An Open-Source File Format for Graph Data Archive/Exchange

Hi, Hacker News! We're excited to announce the release of GraphAr, an open-source file format for archiving and exchanging graph data. The landscape of graph processing systems is fragmented, with various types of systems, including graph databases, graph computation systems, and GNN systems. However, currently, there is no common file format for efficiently storing and exchanging graph data while maintaining its schema and graph semantics. GraphAr is designed to address this issue by providing a simple, lightweight format for storing and exchanging graph data. GraphAr is a flexible and…

GraphAr – An Open-Source File Format for Graph Data Archive/Exchange launched on April 27, 2023 with 5 votes, #2,314 of 4,853 launches that month and more than 50% of that year's launches. The site was still online in September 2026, 3 years on.

What it does

    Hey HN, we want to share HelixDB (https://github.com/HelixDB/helix-db/), a project a college friend and I are working on. It’s a new database that natively intertwines graph and vector types, without sacrificing performance. It’s written in Rust and our initial focus is on supporting RAG. Here’s a video runthrough: https://screen.studio/share/szgQu3yq. Why a hybrid? Vector databases are useful for similarity queries, while graph databases are useful for relationship queries. Each stores data in a way that’s best for its main type of query (e.g.…

    Hey HN, it’s been just over a year since we launched HelixDB (https://news.ycombinator.com/item?id=43975423), a project a friend and I started in college. It’s an OLTP graph database built on object-storage, with native vector search and full-text search (FTS). Why graph, vector and FTS? Graph databases provide a natural cognitive model for data, vectors allow for a semantic understanding of the entities and relationships in the graph, and FTS provides more specific filtering. Many AI-driven applications attempt to combine all of these functionalities by stitching together…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
