Optimizing Application Performance with Connection Pools in Elixir

The video discusses the concept of connection pools and their impact on performance, particularly in high-demand applications utilizing PostgreSQL. It demonstrates how to implement Poolboy in Elixir to create an efficient process pool for managing connections and balancing load. Furthermore, the video showcases the use of Observer for real-time visualization of application structure and performance. A comparison is made between utilizing a pool of processes and scaling instances on Kubernetes, outlining which approach is more beneficial for different application types. This video is aimed at those looking to optimize their applications and leverage Elixir’s capabilities for performance enhancements.
