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 CONCURRENTfor improved write throughput.- Indexing for vector search.
- Improved schema management including better
ALTERsupport and strict column types by default.
Please see the Limbo Database Manual for more information.
💻 Command Line
You can install the latest `limbo` release with:
curl --proto '=https' --tlsv1.2 -LsSf \
https://github.com/tursodatabase/limbo/releases/latest/download/turso_cli-installer.sh | shThen 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
limbo> CREATE TABLE users (id INT PRIMARY KEY, username TEXT);
limbo> INSERT INTO users VALUES (1, 'alice');
limbo> INSERT INTO users VALUES (2, 'bob');
limbo> SELECT * FROM users;
1|alice
2|bobYou can also build and run the latest development version with:
cargo run🦀 Rust
cargo add limboExample 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 limbo-wasmExample usage:
import { Database } from 'limbo-wasm';
const db = new Database('sqlite.db');
const stmt = db.prepare('SELECT * FROM users');
const users = stmt.all();
console.log(users);🐍 Python
pip install pylimboExample 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 limbo'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/limbo
go install github.com/tursodatabase/limboExample usage:
import (
"database/sql"
_ "github.com/tursodatabase/limbo"
)
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.
Turso Database is currently under heavy development and is not ready for production use.
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.
