Type: Post

The article delves into the complexities of caching in computer science, highlighting the challenges of cache invalidation. It discusses the use of Elixir's in-memory caching options while also addressing the limitations in serverless environments. The post introduces Cachex for local caching (L1) and Redis for distributed caching (L2). The author provides a detailed step-by-step guide on creating a custom caching solution using decorators in Elixir. This multi-layered caching approach aims to reduce latency, minimize external requests, and ensure cost efficiency while maintaining system performance during scaling. Code snippets illustrate the setup of Cachex and Redis layers and how to implement decorators for caching.
