hydrods 2.1.0

The official Python client for HydroDB

HydroDB Python Client (hydrods)

The official Python client library for HydroDB - a blazing fast, multi-threaded NoSQL database built in C++17.

HydroDB is designed to outperform single-threaded databases like Redis in highly concurrent environments by utilizing a unified Reader-Writer Starvation-Free Lock Engine, dynamic Fluid Pressure Buckets, and Zero-Latency Asynchronous AOF Persistence.

🚀 Installation

pip install hydrods

💻 Quick Start

from hydrods import HydroDB

# Connect to your HydroDB server (Default: localhost:7379)
db = HydroDB(host='127.0.0.1', port=7379)

# --- Basic Operations ---

# SET a key-value pair
db.set('user:101', 'Anurag Panwar')

# GET the value
name = db.get('user:101')
print(f"Name: {name}")

# DELETE a key
db.delete('user:101')

# --- Range Queries (Ordered Keys) ---

# Fetch all keys between 'a' and 'z'
all_data = db.range('a', 'z')
print(all_data)

# Always close the connection when done
db.close()

⚡ Features

• Raw TCP Sockets: No overhead, blazing fast native TCP connections without blocking bugs.
• RESP Protocol Parser: Automatically parses Redis Serialization Protocol responses directly into Python data structures (Strings, Integers, Dictionaries).
• Thread Pool Compatible: Easily handles high concurrency when paired with Python's threading or connection pools.

🏆 Performance

In direct concurrent benchmarks against standard Redis Event-Loop:

• Faster Single-Threaded Reads: ~26,000 GET RPS natively without async-loop overhead.
• Extreme Concurrency: Maintains highly stable 40,000+ RPS even with 200+ concurrent worker threads constantly reading and writing, thanks to robust std::shared_mutex usage and lock-free thread queues.
