Improving Elixir Application Performance with Cachex Caching

Allan MacGregor's article highlights Elixir's capability to handle concurrency and scale but notes computational tasks can still slow down applications. Caching is presented as a solution for improving performance. The focus is on Cachex, a tailored library for Elixir that offers features such as TTL, fallbacks, and locks. Various caching options in Elixir are mentioned, alongside a detailed guide on integrating Cachex into projects. The article covers caching strategies, handling stale data with TTL and fallbacks, and includes examples of caching in Phoenix apps for database queries, views, and API responses.
