An experimental database written in Rust, focused on learning storage engines, persistence, and query execution.

The Reason

I was wondering one day that how databases actually worked, and thought "why not just make one?". And then I started building EnsoDB to explore database internals, storage mechanisms, indexing data, exploring thread-safe practices.

What It Does

• Implements a persistent data store with tables and databases
• Supports basic CRUD operations with a query language supporting CREATE TABLE, INSERT, SELECT, DELETE
• Provides a CLI interface, along with a TCP client for future client SDKs (currently only Rust SDK available)

Technical Design

• Written in Rust for memory safety and performance
• Uses a log-structured model for storage layer
• Supports background compaction and segmentation

Challenges

• Designing segmentation and compaction without corrupting data
• Trade-offs between simplicty and efficiency
