021 FOUNDATION OVERVIEW

Documentation for 021_FOUNDATION_OVERVIEW from the Foundation repository.

Foundation Layer Overview

The Foundation layer provides a robust set of core services for building reliable, distributed applications in Elixir. It is designed to be a comprehensive toolkit for handling common concerns such as configuration, eventing, telemetry, and process management.

Core Components

The Foundation layer is composed of several key components:

  • Foundation: The main public API for the Foundation layer. It provides a unified interface for initializing, managing, and interacting with all Foundation services.
  • Foundation.Application: The main application supervisor. It manages the lifecycle of all Foundation components in a supervised and fault-tolerant manner.
  • Foundation.Config: A configuration management service that provides a centralized way to manage application configuration.
  • Foundation.Events: An event management and storage service that provides a reliable way to handle and persist events.
  • Foundation.Telemetry: A telemetry and metrics collection service that provides a standardized way to collect and report telemetry data.
  • Foundation.ProcessRegistry: A centralized process registry that provides a way to register and discover processes in a distributed environment.
  • Foundation.ServiceRegistry: A high-level service registration and discovery API that provides a clean interface for managing services.
  • Foundation.Error and Foundation.ErrorContext: A comprehensive error handling and context system that provides a structured way to manage and report errors.
  • Foundation.Infrastructure: A collection of infrastructure services, including circuit breakers, connection managers, and rate limiters.
  • Foundation.Coordination: A set of coordination primitives for building distributed systems, including distributed locks, consensus, barriers, and leader election.

MABEAM

MABEAM (Multi-Agent BEAM) is a feature of the Foundation layer that provides a framework for building multi-agent systems. It includes components for agent management, communication, coordination, and more. MABEAM is designed to be a higher-level abstraction on top of the core Foundation services.

Design Philosophy

The Foundation layer is designed with the following principles in mind:

  • Reliability: The Foundation layer is designed to be highly reliable and fault-tolerant. It uses supervision trees and other OTP principles to ensure that services are automatically restarted in the event of a failure.
  • Scalability: The Foundation layer is designed to be scalable and performant. It uses techniques such as connection pooling and rate limiting to ensure that services can handle a large number of requests.
  • Extensibility: The Foundation layer is designed to be extensible. It provides a set of core services that can be easily extended with custom functionality.
  • Usability: The Foundation layer is designed to be easy to use. It provides a clean and well-documented API that makes it easy to get started.
