Data Caching Methods for 1.2 Billion API Requests/Day

The latest article on the RevenueCat blog focuses on the challenges of data caching and its implementation in engineering systems. Data caching is a technique that allows for frequently used information to be stored in cache memory, significantly enhancing application performance. The article emphasizes that a good caching system should not only provide speed in data access but also maintain consistency and current information. RevenueCat has navigated various caching implementation techniques, ranging from straightforward solutions to more complex algorithms. The solutions applied aim not just to improve performance but also to reduce operational costs. A well-planned caching system is also crucial as it can greatly enhance user experience, allowing applications to respond faster to user queries.
