Introduction to Laravel caching

This post demonstrates the practical application of caching in a Laravel application to optimize database query performance. It introduces the `Cache::remember()` method for implementing application-level caching, showing how to store query results for a specified duration to reduce database load. The post quantifies the performance improvement, showing a reduction in response time from seconds to milliseconds after implementing caching. It also provides instructions for setting up a PlanetScale database for the demonstration and discusses the trade-offs of different cache drivers.
