Skytable is a modern NoSQL database that focuses on performance, flexibility and scalability. Our goal is to deliver a rock-solid database that you can use as the foundation for your next application — minus the gimmicks.
Skytable makes every attempt to remove the gotchas from SQL-systems. For example, nonempty models and spaces cannot be dropped and BlueQL is designed to greatly deter SQL injection vulnerabilities with a new mandatory parameterization design and several other secure query language design principles.
Every component in Skytable has been engineered from the ground up to meet our design goals. Skytable uses BlueQLTM which is our own new in-house query language designed from the ground up for a clean, powerful, modern and secure querying experience and is generally more secure than SQL.
Skytable works with structured and semi-structured data. We're currently working on supporting unstructured data.
You can read more about Skytable's architecture, including information on the clustering and HA implementation that we're currently working on, and limitations on this page.
- Spaces, models and more: For flexible data definition
- Powerful querying with BlueQL: A modern query language, designed for the 21st century
- Rich data modeling: Use
models to define data with complex types, collections and more - Performant, in and out of the box: Heavily multithreaded and optimized
- Secure, query in and response out: BlueQL is designed to strongly deter query injection pathways
- SQL minus the gotchas: Ever done a
DROP TABLE usersand lost all data? That won't happen in Skytable. - Designed to scale by enforcing best practices: If you're building with Skytable today, the practices you'll learn here will let you easily take on the job of building large scale systems

- Set up Skytable on your machine: You'll need to download a bundled release file from the releases page. Unzip the files and you're ready to go.
- Start the database server:
./skyd --auth-root-password <password>with your choice of a password for therootaccount. Therootaccount is just like arootaccount on Unix based systems that has control over everything. - Start the interactive client REPL:
./skyshand then enter your password. - You're ready to run queries!
For a more detailed guide on installation and deployment, follow the guide here.
Skytable has SPACEs instead of DATABASEs due to signficant operational differences (and because SPACEs store a lot more than tabular data).
With the REPL started, follow this guide:
- Create a
spaceand switch to it:CREATE SPACE myspace USE myspace
- Create a
model:The rough representation for this in Rust would be:CREATE MODEL myspace.mymodel(username: string, password: string, notes: list { type: string })
pub struct MyModel { username: String, password: Strin, notes: Vec<String>, }
INSERTsome data:INSERT INTO mymodel('sayan', 'pass123', [])
UPDATEsome data:UPDATE mymodel SET notes += "my first note" WHERE username = 'sayan'
SELECTsome dataSELECT * FROM mymodel WHERE username = 'sayan'
- Poke around! And then make sure you read the documentation learn BlueQL.
For a complete guide on Skytable, it's architecture, BlueQL, queries and more we strongly recommend you to read the documentation here.
While you're seeing strings and other values being used here, this is so because the REPL client smartly parameterizes queries behind the scenes. BlueQL has mandatory parameterization. (See below to see how the Rust client handles this)
You need a client driver to use Skytable in your programs. Officially, we maintain a regularly updated Rust client driver which is liberally license under the Apache-2.0 license so that you can use it anywhere.
Using the Rust client driver, it's very straightforward to run queries thanks to Rust's powerful type system and macros:
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 it!
}You can find more information on client drivers on this page. If you want to help write a client driver for your language of choice, we're here to support your work. Please reach out to: hey@skytable.io or leave a message on our Discord server!
We exclusively use Discord for most real-time communications — you can chat with developers, maintainers, and our amazing users! Outside that, we recommend that you use our GitHub Discussions page for any questions or open a new issue if you think you've found a bug.
We're here to help!
