AionDB

What it does

AionDB is a PostgreSQL-compatible multimodal database in Rust that combines relational records, graph relationships, and vector search in one engine.

aiondb v0.3 vector update AionDB v0.3 is live: vector search becomes a first-class engine surface with pgvector-style SQL, HNSW, IVF-flat, Qdrant-style filters, and published recall/latency benchmarks. See the v0.3 vector update . PostgreSQL wire / ORM-compatible / SQL + graph + vector AionDB v0.3 brings pgvector-style SQL, HNSW, IVF-flat, Qdrant-style filters, graph relationships, and relational records into one Rust engine. MATCH (u:User {tenant_id: 100})-[:WROTE]->(d:Document) -[:CITES]->(ref:Document) WHERE d.kind = 'runbook' RETURN d.title, ref.title, l2_distance (d.embedding, '[0.1,0.8,0.2]') AS dist, u.tenant_id ORDER BY dist ASC LIMIT 5; Normal app stack. pgwire, ORMs, migrations,…from aiondb.xyz

  HelixDB – Open-source vector-graph database for AI applications (Rust)2025 · github.com · ▲237

  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.…

  Talanoa▲346

  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…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
