Ryx Architecture

- -Your Python queries are compiled to SQL in Rust, executed by sqlx, and decoded back — all without blocking the Python event loop. -To achieve near-native performance, Ryx uses a **multi-crate workspace architecture**: -- `ryx-query`: A standalone, ultra-fast SQL compiler. -- `ryx-backend`: High-performance database drivers using **Enum Dispatch** (no vtables) to eliminate runtime overhead. -- `ryx-core`: Shared base types and the core ORM engine. -- `ryx-python`: Optimized PyO3 bindings. +``` + Python (ryx-python) Rust (ryx-rs) + │ │ + PyO3 bridge ────────╗ no pyo3 + │ ║ │ + ┌─────┴─────────────║───────────┴──────┐ + │ ryx-core ║ ryx-common │ + └─────┬─────────────║───────────┬──────┘ + │ ║ │ + ┌─────┴─────────────║───────────┴──────┐ + │ ryx-query (SQL compiler) │ + └───────────────────┬──────────────────┘ + │ + ┌───────────────────┴──────────────────┐ + │ ryx-backend (sqlx) │ + │ Postgres · MySQL · SQLite │ + └──────────────────────────────────────┘ +``` -**Key Performance Innovation**: Ryx uses a **Zero-Allocation Row View** system. Instead of creating a Python dictionary for every row, we use a shared column mapping and a flat value vector, drastically reducing heap allocations and GC pressure during large fetches. - ## Performance - -Benchmark of 1 000 rows on SQLite (lower is better): - -| Operation | Ryx ORM | SQLAlchemy ORM | SQLAlchemy Core | Ryx raw | -|-----------|--------:|---------------:|----------------:|--------:| -| **bulk_create** | 0.0074 s | 0.1696 s | 0.0022 s | 0.0011 s | -| **bulk_update** | 0.0023 s | 0.0018 s | 0.0010 s | 0.0005 s | -| **bulk_delete** | 0.0005 s | 0.0012 s | 0.0009 s | 0.0004 s | -| **filter + order + limit** | 0.0009 s | 0.0019 s | 0.0008 s | 0.0004 s | -| **aggregate** | 0.0002 s | 0.0015 s | 0.0005 s | 0.0001 s | - -Ryx ORM is **16× faster** than SQLAlchemy ORM on bulk inserts and **2× faster** on deletes — while keeping the same Django-style API.
