Unlocking the Potential of OTP: Proven Strategies for Application Dev
summary
Shows concrete patterns and measurable results: uses Task.async_stream and a Task.Supervisor to run email sends and currency fetchers concurrently (different PIDs for each worker), converting a 10s sequential flow to reduced 10s to 4s; demonstrates that placing heavy work in an Agent blocks the caller (Agent blocks caller with 4s work); moves initialization work into a GenServer using GenServer handle_continue avoids startup blocking; and wires tasks under supervision so Task.Supervisor restarts failed email sends for fault tolerance.
