# λykiaDB [](https://github.com/lykia-rs/lykiadb/actions/workflows/ci.yml)

Lykia is a toy document database basically written for educational purposes. It is planned to be a modest mixture of popular kids in town (e.g. SurrealDB). ## Overview - Written in Rust - A weird scripting and query language, combination of PHP and SQL. Built based on the language "Lox" which is explained in the famous book, Crafting Interpreters. - A subset of JSON data types in both scripting language itself and storage - In-disk and in-memory storage - ACID compliance - Replication ## Roadmap - [x] Core scripting language - [ ] A minimal standard library (in progress) - [ ] SQL parsing (in progress) - [ ] Query planning - [ ] Async runtime/event loop - [ ] In-memory storage engine - [ ] Persistent storage engine (Bitcask) - [ ] Transaction management with MVCC - [ ] B-Tree implementation for indexes - [ ] Basic replication with Raft ## Getting Started To use Lykia, you can download the latest release from the GitHub releases page. REPL: ```shell $ cargo run ``` Alternatively, you can run a Lykia script by passing its name as the first argument. ```shell $ cargo run examples/fib.ly ``` ## License Lykia is licensed under the Apache License, Version 2.0.
