🔗 LiveStash Performance Tests

LiveView is an amazing Elixir framework, but what happens when your connection drops? Krzysztof Nalepa and Filip Węgrzyn dive into the challenges faced with state management during reconnections in Phoenix LiveView applications. They present the LiveStash library, which addresses these issues by persisting LiveView state seamlessly. The article details various adapters for LiveStash, including ETS, Redis, Browser memory, and Mnesia, each with unique strengths and weaknesses.

To understand how these adapters perform under pressure, the authors designed stress tests using 25,000 virtual users across different Time-To-Live configurations. The results provide valuable insights into memory usage, network throughput, and Erlang process behavior. This testing highlights the critical importance of architecture choices in achieving reliable and efficient state management during user reconnections. The findings serve as a guide for developers looking to optimize their applications with LiveStash.
