👉 Expiration engineering is a specialized field within software engineering that focuses on designing systems to manage and control the lifecycle of resources, particularly those with limited lifespans or expiration dates. This includes handling tasks such as automatically decommissioning or archiving data, releasing memory, and ensuring that temporary resources are properly cleaned up after their intended use. By implementing expiration policies, engineers can prevent resource leaks, optimize system performance, and maintain data integrity. This approach is crucial in environments where resources are scarce or costly, ensuring that systems operate efficiently and sustainably over time. Expiration engineering often involves creating mechanisms for setting expiration times, monitoring resource usage, and triggering cleanup processes when resources reach their end-of-life.
