Redis-Backed Data Structures for Python

Redis-backed Python data structures that function like built-ins but store data on a Redis server.

• Facilitates shared access across distributed systems
• Avoids the transfer of large pickle objects and pickling/unpickling overhead

---

🚀 Features

• Drop-in Replacements: Use familiar Python data structures (list, dict, set, etc.) with minimal changes to your code.
• Redis-Powered: Data is stored on the Redis server, enabling easy sharing across processes, services, or systems.
• Seamless Integration: Works like native Python data structures while leveraging Redis for distributed use cases.

---

📥 Installation

Install the library using pip:

pip install py_redis_ds

---

💡 Usage

Here’s a quick example of how to use a Redis-backed list:

from py_redis_ds.builtins import List
from redis import Redis

redis = Redis()

# Initialize a Redis-backed list
rlist = List(name="my_shared_list", redis=redis)

# Add elements
rlist.append("Hello")
rlist.append("World")

# Access elements
print(rlist[0])  # Output: Hello

# Iterate through the list
for item in rlist:
    print(item)

# Shared access in another script or service
rlist2 = List(name="my_shared_list", redis=redis)
print(rlist2[1])  # Output: World

🌟 Why Use Redis-Backed Structures?

• Shared State: Easily share data between processes, microservices, or distributed systems.
• Scalability: Offload data storage to Redis, reducing memory usage in individual processes.
• Simplicity: Use familiar Python syntax while leveraging Redis's power.
