AetheriusDB User Guide

A high-performance, memory-mapped database with SQL, native vectors, in-database compute, and time-travel — this guide shows you how to use it.

Quickstart What is AetheriusDB?

Follow the workflow

Define your data

Create typed tables, native vector and semantic types, schema-as-code.

Load data

Stream, bulk-load via Arrow, capture change data, connect sources.

Query data

ANSI SQL, vector search, pivots, indexing, and performance knobs.

Compute in-database

Deploy WASM cells that run logic next to the data.

Secure & operate

RBAC/RLS, encryption, observability, and clients.

Reference

SQL grammar, data types, functions, and the configuration matrix.

Every feature carries an availability label

So you always know what is on by default, what is opt-in behind a flag, what is beta, and what is still roadmap — before you build on it.
