A supervisor that restarts children endlessly usually signals a mismatched restart strategy or intensity limit. Match the strategy to the failure domain and tune restarts before the cascade reaches the top of the tree.
Use a supervised Elixir GenServer to serialize writes to a mutable external resource, with timeouts, input validation, and operational checks.
Decide between Twilio Verify and a custom OTP on Programmable Messaging for phone-number verification, with cost, fraud, and implementation trade-offs.
Learn how to choose between GenServer.call, cast, and handle_info to build responsive stateful services in Elixir without blocking your event loop.
A diagnostic guide for intermittent GenServer.call timeouts in Elixir, covering caller timeouts, mailbox backlog, blocked callbacks, and escalation criteria.
Your gen_server serializes requests by design. Learn when that guarantee helps and when to refactor to async or multi-process patterns for throughput.
Task.async_stream caps concurrent work on an enumerable, isolates per-item failures, and preserves order by default. Learn the trade-offs and how to verify behavior in your Elixir version.
Learn how to implement type-safe concurrent actors in Gleam using gleam/otp, including state management, supervision strategies, and BEAM VM integration.
Learn how OTP supervision trees automatically restart crashed Erlang processes, using a chat‑server example to show design, a worked test, trade‑offs, and next steps.
