kite_sql

SQL as a Function for Rust

Introduction

KiteSQL is a lightweight embedded database inspired by MyRocks and SQLite and completely coded in Rust. It aims to provide a more user-friendly, lightweight, and low-loss RDBMS for Rust programming so that the APP does not rely on other complex components. It can perform complex relational data operations.

Key Features

• A lightweight embedded SQL database fully rewritten in Rust
• Higher write speed, more user-friendly API
• All metadata and actual data in KV Storage, and there is no state component (e.g. system table) in the middle
• Supports extending storage for customized workloads
• Supports most of the SQL 2016 syntax

Examples

let kite_sql = DataBaseBuilder::path("./data").build()?;

kite_sql
    .run("create table if not exists t1 (c1 int primary key, c2 int)")?
    .done()?;
kite_sql
    .run("insert into t1 values(0, 0), (1, 1)")?
    .done()?;

for tuple in kite_sql.run("select * from t1")? {
    println!("{:?}", tuple?);
}
