This repository provides a simple implementation of the Singleton pattern in Python. The Singleton pattern ensures that only one instance of a class is created throughout the application and provides a global point of access to that instance.
• Thread-safe Singleton using a Lock.
• Simple and reusable design.
• Demonstrates how to ensure a single instance with shared state.
The Singleton class:
• Uses the __new__ method to control instance creation.
• Ensures thread safety with a Lock.
• Shares the spark and log attributes between all instances.
• Database Connections: Ensure only one connection pool is active.
• Logging: Maintain a single logging instance for consistent application-wide logs.
• Caching: Manage shared resources like in-memory cache.
Feel free to reach out with any questions or feedback.
