Turso Database is a project to build the next evolution of SQLite

4 months ago 12

Turso Database is an in-process SQL database, compatible with SQLite.

Turso Database is a work-in-progress, in-process OLTP database engine library written in Rust that has:

SQLite compatibility [doc] for SQL dialect, file formats, and the C API
Language bindings for JavaScript/WebAssembly, Rust, Go, Python, and Java
Asynchronous I/O support on Linux with io_uring
OS support for Linux, macOS, and Windows

In the future, we will be also working on:

BEGIN CONCURRENT for improved write throughput.
Indexing for vector search.
Improved schema management including better ALTER support and strict column types by default.

Please see the Turso Database Manual for more information.

💻 Command Line
You can install the latest `turso` release with:

curl --proto '=https' --tlsv1.2 -LsSf \ https://github.com/tursodatabase/turso/releases/latest/download/turso_cli-installer.sh | sh

Then launch the shell to execute SQL statements:

Turso Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database turso> CREATE TABLE users (id INT, username TEXT); turso> INSERT INTO users VALUES (1, 'alice'); turso> INSERT INTO users VALUES (2, 'bob'); turso> SELECT * FROM users; 1|alice 2|bob

You can also build and run the latest development version with:

🦀 Rust

Example usage:

let db = Builder::new_local("sqlite.db").build().await?; let conn = db.connect()?; let res = conn.query("SELECT * FROM users", ()).await?;

✨ JavaScript

npm i @tursodatabase/turso

Example usage:

import { Database } from '@tursodatabase/turso'; const db = new Database('sqlite.db'); const stmt = db.prepare('SELECT * FROM users'); const users = stmt.all(); console.log(users);

🐍 Python

Example usage:

import turso con = turso.connect("sqlite.db") cur = con.cursor() res = cur.execute("SELECT * FROM users") print(res.fetchone())

🐹 Go

Clone the repository
Build the library and set your LD_LIBRARY_PATH to include turso's target directory

cargo build --package limbo-go export LD_LIBRARY_PATH=/path/to/limbo/target/debug:$LD_LIBRARY_PATH

Use the driver

go get github.com/tursodatabase/turso go install github.com/tursodatabase/turso

Example usage:

import ( "database/sql" _ "github.com/tursodatabase/turso" ) conn, _ = sql.Open("sqlite3", "sqlite.db") defer conn.Close() stmt, _ := conn.Prepare("select * from users") defer stmt.Close() rows, _ = stmt.Query() for rows.Next() { var id int var username string _ := rows.Scan(&id, &username) fmt.Printf("User: ID: %d, Username: %s\n", id, username) }

☕️ Java

We integrated Turso Database into JDBC. For detailed instructions on how to use Turso Database with java, please refer to the README.md under bindings/java.

We'd love to have you contribute to Turso Database! Please check out the contribution guide to get started.

Is Turso Database ready for production use?

Turso Database is currently under heavy development and is not ready for production use.

How is Turso Database different from Turso's libSQL?

Turso Database is a project to build the next evolution of SQLite in Rust, with a strong open contribution focus and features like native async support, vector search, and more. The libSQL project is also an attempt to evolve SQLite in a similar direction, but through a fork rather than a rewrite.

Rewriting SQLite in Rust started as an unassuming experiment, and due to its incredible success, replaces libSQL as our intended direction. At this point, libSQL is production ready, Turso Database is not - although it is evolving rapidly. More details here.
