Skytable is a modern NoSQL database designed to offer high performance, flexibility, and scalability. It is primarily an in-memory, wide-column based database with support for additional data models, powered by its own query language, BlueQL.

What is Skytable?

Skytable is best suited for applications needing to store large-scale data with high performance and low latency. It uses its own storage engine and enables querying through BlueQL, which builds on top of SQL to enhance security and flexibility.

  • Spaces and Models: Provides flexible data definition.
  • Powerful Querying with BlueQL: A modern query language based on SQL.
  • Rich Data Modeling: Use models to define data with complex types and collections.
  • High Performance: Utilizes multithreading and optimized write batching.
  • Security: BlueQL is designed to deter query injection pathways.
  • Best Practices Enforcement: Learn performant system-building practices with Skytable.

Getting Started

  1. Set up Skytable: Download a release from the releases page. Unzip the files.
  2. Start the database server:
    ./skyd --auth-root-password <password>
    Replace <password> with your chosen password for the root account.
  3. Start the interactive client REPL:
    Then enter your password.
  4. Run queries!

For detailed installation and deployment instructions, follow this guide.

Using Skytable

Skytable uses SPACEs instead of DATABASEs.

  1. Create a space and switch to it:
    CREATE SPACE myspace;
    USE myspace;
  2. Create a model:
    CREATE MODEL myspace.mymodel(username: string, password: string, notes: list { type: string });
  3. Insert data:
    INSERT INTO mymodel('sayan', 'pass123', []);
  4. Update data:
    UPDATE mymodel SET notes += "my first note" WHERE username = 'sayan';
  5. Select data:
    SELECT * FROM mymodel WHERE username = 'sayan';

Learn more about BlueQL and Skytable usage in the documentation.

Client Drivers

Skytable provides a Rust client driver for easy integration. Here's an example of using the Rust client driver:

use skytable::{Config, query};
fn main() {
    let mut db = Config::new_default("username", "password").connect().unwrap();
    let query = query!("select username, password from myspace.mymodel where username = ?", "sayan");
    let (username, password): (String, Vec<u8>) = db.query_parse(&query).unwrap();
    // Do something with the data
