Supervisor Patterns

Coming Soon

This lesson will teach you how to build supervision trees that automatically recover from failures. You’ll learn how to:

• Design supervision strategies (one_for_one, one_for_all, rest_for_one)
• Configure restart policies and limits
• Implement fault isolation and recovery
• Monitor and manage child processes
• Build resilient architecture for your chat server

What You’ll Build

By the end of this lesson, you’ll have implemented:

• A chat room supervisor managing multiple rooms
• Automatic restart policies for failed processes
• Fault isolation to prevent cascade failures
• Monitoring and alerting for system health
• A bulletproof foundation for your chat server

Key Concepts Preview

    ChildSpecs = [
        #{id => chat_room_manager,
          start => {chat_room_manager, start_link, []},
          restart => permanent,
          shutdown => 5000,
          type => worker}
    ],
    {ok, {#{strategy => one_for_one, intensity => 5, period => 10}, ChildSpecs}}.

This lesson builds on the GenServer implementation from Lesson 11 and prepares you for the TCP socket programming we’ll explore in Lesson 13.
