qmvir

QMvir v6.2.3 — Hybrid AI-native database: OLTP + OLAP + full-text search + vector search in one Rust engine. PostgreSQL wire protocol. Production Multi-DC Enterprise Certified (optional HA cluster).

What's new in 6.2.3

• Fix PG wire new_session() registration so node-pg connection pools can INSERT/UPDATE/DELETE (was Session not registered on connection 2+)

What's new in 6.2.2

• npm README sync with published release docs

What's new in 6.2.1

• Faster LIKE '%…%' id-only scans (packed int64 + columnar bridge)
• Release pipeline fix: npm postinstall downloads GitHub binaries matching package.json version (no stale 6.2.0 bins)

Install

npm install [email protected]
# or global CLI
npm install -g qmvir
qm --version   # qm 6.2.3

Postinstall downloads the native binary (~8–13 MB) for your platform from GitHub releases.

Linux and Windows binaries are not bundled in the npm package (that would ship ~70 MB for all platforms). After npm install, scripts/postinstall.js fetches exactly one binary:

| Platform | Downloaded asset | |----------|------------------| | macOS Apple Silicon | qm-macos-arm64 | | macOS Intel | qm-macos-x86_64 | | Linux x86_64 | qm-linux-x86_64 | | Linux ARM64 | qm-linux-aarch64 | | Windows x86_64 | qm-windows-x86_64.exe | | Windows ARM64 | qm-windows-aarch64.exe |

If a cached binary reports a different version, postinstall re-downloads automatically.

Quick start

qm --data-dir ./data start --admin-password secret
psql -h 127.0.0.1 -p 55433 -U admin -d qm

CREATE TABLE users (id INT PRIMARY KEY, name TEXT);
INSERT INTO users VALUES (1, 'Alice');
SELECT * FROM users;

SDK (JavaScript / TypeScript)

import { QMClient } from "qmvir";

const qm = new QMClient("http://localhost:8400", { apiKey: "your-key" });
const rows = await qm.find("users", { where: { status: "active" }, limit: 10 });
const hits = await qm.search("articles", "machine learning", { strategy: "hybrid", limit: 20 });
