Building Z-RevixDB Without Dependencies: What We Had to Rebuild

Описание и применение

Z-RevixDB – это версия‑контролируемая база данных, построенная без внешних зависимостей, использующая только стандартную библиотеку Python. Она хранит все версии записей, обеспечивает аудит, поиск, сравнение и восстановление данных, демонстрируя, что большинство привычных функций можно реализовать самостоятельно.

Задача

Develop a versioned data storage and recovery platform without relying on external dependencies, ensuring full auditability and recoverability while maintaining performance.

Результат

Z-RevixDB delivers a fully versioned, auditable, and recoverable data store without external dependencies, demonstrating that standard library primitives can replace common third‑party packages.

Рабочий процесс

• 1. Replace HTTP frameworks with http.server and custom routing.
• 2. Use sqlite3 for persistent storage of versioned records.
• 3. Implement custom inverted index for search (tokenization, prefix lookup, TF‑IDF ranking).
• 4. Build version comparison using difflib and custom logic.
• 5. Add integrity verification with hashlib hashes.
• 6. Record audit events and expose filtering API.
• 7. Test recovery by restoring from a previous version without losing history.

Доказательства

We used the primitives available in the language itself and implemented the application-specific functionality ourselves.

Источник

Instead of installing our preferred tools… we started asking a different question: What does this package actually provide, and can we build the required part ourselves using the standard library?
