Description: A TTL (Time To Live) index is a special type of index used in databases that allows for the automatic deletion of documents or records after a specified period of time. This mechanism is particularly useful in applications where data has a limited lifespan, such as in caching systems, temporary logs, or session data. The main feature of a TTL index is its ability to manage data expiration without manual intervention, optimizing database performance and reducing unnecessary storage. By setting a lifespan for each document, developers can ensure that the database remains clean and efficient by automatically removing records that are no longer relevant. This approach not only improves storage management but can also contribute to data security and privacy by ensuring that sensitive information does not remain stored beyond its necessity. In summary, the TTL index is a powerful tool for data management in environments where the temporality of data is a critical factor.
