Show HN: SQL++ – 5x faster than Prisma (Rust)

https://github.com/sinisterMage/sqlpp
2•SinisterMage2•2mo ago
I built SQL++, a type-safe SQL library for Rust using PostgreSQL's binary protocol.

Benchmarks vs Prisma (5,000-10,000 queries): - Simple queries: 1.5x faster - Complex aggregations: 19.9x faster - Batch inserts: 5.6x faster - Average: 5x faster

One benchmark didn't finish in Prisma (crashed), SQL++ completed in 2.5min.

Why faster: 1. No runtime query building - validates once, caches forever 2. Zero ORM overhead - direct struct mapping 3. Binary protocol - implemented PostgreSQL wire protocol from scratch

Currently supports: - Full SQL (CTEs, window functions, JOINs, subqueries) - DDL (CREATE/ALTER/DROP TABLE, indexes) - ~60% of SQL spec

Limitations: - PostgreSQL only - v0.1 (expect bugs) - No ORM relationships (by design)

Built as a high school project. Feedback welcome!

> 3. Binary protocol - implemented PostgreSQL wire protocol from scratch

Any chance of contributing to https://crates.io/crates/pgwire ? pgwire has been great on the server end for me, and it would make sense to have a single high-quality implementation of the whole protocol.

Also, your SQL parser is gonna miss out on a lot of the very complex language. Have you seen https://crates.io/crates/sqlparser ?

I don't quite understand the name. Sort of follows the "I wrote this in C++" convention of naming.
alloysmila•2mo ago
What is the point of comparing with prisma? prisma is javascript, it's already likely to be slower.
