λykiaDB

Lykia is a document database management system built for educational purposes. The famous book, Crafting Interpreters, was the main source of inspiration for the project. It turned into a database, though.

Overview

• 100% safe Rust, #BlazinglyFast
• A weird scripting and query language, combination of JavaScript and SQL. The language is a separate module thus can be used without the database.
• A subset of JSON data types in both scripting language itself and storage
• In-disk and in-memory storage
• ACID compliance
• Replication

Roadmap

• Core scripting language + DML/DDL SQL
• A minimal standard library
• Runtime
• Playground app
• Query binding and planning (in progress)
• LSM storage engine (based on mini-lsm)
• MVCC for transaction management (based on mini-lsm)
• Plan optimization

## More ambitious roadmap:

• Basic replication with Raft
