The article discusses the use of Redis, a high-performance NoSQL database, as a primary datastore in a Spring application. It highlights the importance of configuring time-to-live (TTL) for objects stored in Redis, particularly short-lived ones like CardInfoEntity. Three methods to set TTL are outlined, with a focus on the advantages of using KeyspaceConfiguration for flexibility over hardcoded values or additional fields. This enables dynamic adjustments in application.yml without altering the core business logic.
Redis offers a robust solution for storing short-lived objects, automatically managing their lifecycle using time-to-live (TTL) configurations in a Spring application.
