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

## Primary goals
- [x] Core scripting language + DML/DDL SQL
- [x] Client and server apps
- [x] A minimal standard library
- [ ] Query planning and binding (in progress)
- [ ] Query execution (in progress)
- [ ] Persistent storage engine (in progress)
- [ ] Transactions and multi-version concurrency control

## Phase 2 goals
- [ ] Replication with Raft
- [ ] JIT execution for expression evaluation
- [ ] Query optimization
    
## Non-goals
- LykiaDB is not (and will not be) a production-grade database.
