What is Temporal?

Temporal is a durable execution platform that makes your code crash-proof by automatically persisting workflow state and handling failures transparently. Think of it as a way to write distributed systems code as if failure doesn't exist.

Core Concepts

🔄 Durable Execution

• State Persistence: Every step of your workflow is automatically saved to a database
• Automatic Recovery: If your code crashes, it resumes exactly where it left off
• No Lost Progress: Zero data loss even during infrastructure failures

🏗️ Architecture Components

Workflows: The main business logic that orchestrates your application flow

• Written in regular TypeScript/Python/Go/Java code
• Deterministic and replayable
• Can run for minutes, hours, days, or even years

Activities: Individual tasks that interact with external systems

• Handle API calls, database operations, file I/O
• Automatic retries with exponential backoff
• Timeout handling and error recovery

Workers: Processes that execute your workflows and activities

• Can be scaled horizontally
• Pull tasks from queues automatically
