Using an in-memory side cache is a prevalent strategy in web applications to enhance response times and reduce database load. This method is cost-effective and adaptable, allowing for improvements in data retrieval without complex cache invalidation issues. While scaling the cache often seems like a solution during high traffic periods, persistent performance challenges can arise. This article discusses practical experiences and strategies for cache management under these pressures, emphasizing solutions that are viable for smaller teams and organizations.
Using an in-memory side cache to improve response times and alleviate the load on a database is one of the most common design patterns seen in web applications.
As system load increases, challenges inevitably emerge... however, the performance issues persist, necessitating a careful re-evaluation of our approach to caching under high demand.
