Description: A temporary key is a key in Redis that is set to expire after a certain period. This mechanism allows developers to manage the lifespan of stored data, which is especially useful in applications where information has limited value over time. Temporary keys are a fundamental feature of Redis, an in-memory storage system widely used for its speed and efficiency. By setting an expiration time, users can automatically free up memory space and prevent the accumulation of stale data. Additionally, temporary keys can be configured with different expiration times, ranging from seconds to days, providing flexibility in data management. This functionality is essential in scenarios such as user sessions, data caching, and message queues, where the temporality of information is crucial for application performance and relevance.
