Understand how to implement stateful processes using GenServer, balancing synchronous calls and asynchronous casts to build resilient OTP applications.
Stop blocking your Elixir processes. Learn when to use GenServer.call versus GenServer.cast to balance system responsiveness with state consistency.
Learn when to use GenServer.call vs GenServer.cast in Elixir. We explore the trade-offs between synchronous consistency and asynchronous throughput with a practical rate-limiter example.
Deciding between GenServer and spawned processes in Erlang involves balancing overhead against operational stability. This guide compares both for state management.
GenServer turns a module into a concurrent service that encapsulates state, handles messages, and integrates with OTP supervision. This blog walks through a counter example, discusses trade‑offs, and offers actionable steps for Elixir developers.
