PostgreSQL wire / ORM-compatible / SQL + graph + vector
AionDB
PostgreSQL tooling for applications that need relational records, graph relationships, and vector search in one Rust engine.

>> PostgreSQL ecosystem path
Use normal ORMs and migration tools through pgwire.
Django is the only excluded ORM today: its harness catches a NOT NULL migration enforcement gap.
>> Data model
Built for application data that outgrows one shape.
Relational state
Tables remain the source of truth, queried through SQL and PostgreSQL-compatible clients.
Connected data
Graph labels and Cypher-style patterns are available over ordinary application records.
Semantic retrieval
Vector columns and distance functions live beside metadata instead of in a detached service.
Local integration
The engine can run as a server over pgwire or through the embedded Rust API.
>> Measured, not universal claims
Performance position
AionDB is not presented as universally faster than mature single-purpose systems. The useful claim is narrower: it already performs competitively on many measured SQL workloads, is often materially faster than SurrealDB on the measured SQL, graph, and hybrid workloads in the public harnesses, and publishes the raw benchmark snapshots used by the docs.
See Benchmarks and Benchmark Results for exact measured cases.
>> Alpha boundaries
What AionDB does not claim.
PostgreSQL replacement
No. PostgreSQL remains the compatibility and operational maturity reference.
Production-ready cluster
No. Distributed and HA modules are internal or experimental in v0.1.
Every ORM works
No. Many harnesses pass now, but every app still needs feature-by-feature validation.
Best on every benchmark
No. The project publishes reproducible benchmark snapshots instead of universal speed claims.
