☄️ Lazarus Data Store

Lazarus Data Store is a high performance object container data store HTTP server implemented in C++ for GNU/Linux. It’s designed for speed, persistence, and simplicity, built on top of RocksDB.

🧩 What is Lazarus DS?

Lazarus DS is an object container store:

• 📦 Containers act like logical buckets.
• 🔑 Each container holds objects stored as key → value pairs (IDs → byte streams).
• 🌐 All operations are exposed via a lightweight HTTP API.
• ⚡ Backed by RocksDB for persistence and performance.

---

🏗️ Architecture

Lazarus DS is split into three conceptual layers:

🌐 HTTP Layer

• Provides REST-style endpoints for containers and objects.
• Responsible for request handling and translating HTTP into storage operations.

⚙️ Storage Engine

• Manages containers (create, drop, list) and objects (insert, get, delete).
• Maps containers directly to RocksDB column families.
• Ensures error handling and logging are consistent.

💾 Persistence

• RocksDB handles the heavy lifting: WAL, SST files, compaction, caching.
• Tuned for parallelism and predictable performance under load.

---

🔑 Features

• 🗂️ Multiple containers via RocksDB column families.
• 📝 Object CRUD (create, retrieve, update, delete) via simple endpoints.
• 🚀 Performance-tuned RocksDB configs (parallelism, block cache).
• 📊 Clear status codes and logging on every operation.
• 🐧 Built for Linux servers.

🌐 HTTP API Overview

Containers

• PUT /lazarus/network/container_endpoint/ → create container
• DELETE /lazarus/network/container_endpoint/ → delete container

Objects

• POST /lazarus/network/object_endpoint/ → insert object
• GET /lazarus/network/object_endpoint/ → fetch object
• DELETE /lazarus/network/object_endpoint/ → remove object

⚡ Python SDK

A Python client lives in sdk/python.

Quick example:

from lazarus_client import LazarusClient

client = LazarusClient(port=8080)

client.create_container("users")
client.insert_object("users", "user123", '{"name": "Alice"}')
print(client.get_object("users", "user123"))
client.delete_object("users", "user123")
client.delete_container("users")
