SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Complex Erlang/OTP production tasks — including BEAM process orchestration, testing, releases, upgrades, and distributed runtime behavior — often require deep domain knowledge and careful risk management to avoid outages.

Core Features & Use Cases

  • Expert guidance on OTP design, supervision trees, process ownership, links/monitors, and runtime behavior.
  • Rebar3 project layout, release configuration, and dependency resolution with safe upgrade pathways.
  • Upgrade safety, testing strategies, and distributed-node considerations for hot-code upgrades and state compatibility.

Quick Start

Upgrade a running Erlang/OTP application using rebar3 with a safe hot-code upgrade, and outline the minimal steps, risks, and validation checks

Frequently Asked Questions about erlang-expert

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I perform a safe hot-code upgrade in a distributed Erlang/OTP deployment?▼

To perform a safe hot-code upgrade in a distributed Erlang/OTP deployment, you must validate state compatibility across nodes and outline minimal rebar3 steps, runtime risks, and validation checks.

What are common production risks in Erlang/OTP supervision trees and how do I mitigate them?▼

Common production risks in Erlang/OTP supervision trees involve process ownership and link failures, which you can mitigate by applying correct OTP behaviors and monitoring runtime behavior to prevent outages.

How does rebar3 handle release configuration and dependency resolution for Erlang applications?▼

Rebar3 handles release configuration by standardizing project layout and resolving dependencies, providing safe upgrade pathways to ensure environment-aware deployment and functional design correctness.

What testing strategies should I use for BEAM process orchestration and hot-code upgrades?▼

Testing strategies for BEAM process orchestration and hot-code upgrades should integrate environment-aware validation checks to ensure state compatibility and design correctness across distributed nodes.

When do I need to use OTP behaviors and monitors instead of plain Erlang processes?▼

You need to use OTP behaviors and monitors instead of plain Erlang processes when building robust distributed systems, as they provide necessary supervision tree integration, process ownership, and runtime fault tolerance.
