Internals de bases de datos en Rust para Jeresoft Academy: B-Tree, LSM, índices, transacciones, MVCC, WAL y recovery.

A SQL database hewn from bedrock — built from scratch in Rust. Custom LSM engine, WAL journal, page cache, and SQL execution. Speaks the Postgres wire protocol. A craft project, every layer built on my own terms.

trying to learn DB internals by building a simple storage engine

A custom relational/document database storage and query engine built from scratch exploring B-Trees, indexing, and disk persistence.

A minimal educational relational database management system (RDBMS) implemented in Java 17. The project demonstrates a custom SQL processing pipeline, including lexer, parser, semantic analysis, query planning, optimization, and execution. It features a storage engine with heap pages, a buffer pool, and supports indexing using B-trees and Hash
