Temporal

Temporal

Temporal is a durable execution platform that makes it simple to write long-running, fault-tolerant business logic. Applications that used to require complex state machines, queues, and cron jobs can now be written as simple procedural code.

Key Features

• Durable workflows: Code that survives process restarts, infrastructure failures, and deployments automatically
• Language-native SDKs: Python, Go, Java, TypeScript, .NET, PHP — workflows written in your existing language
• Event history: Full replay-based execution with complete audit trail
• Scalability: Battle-tested at hyperscaler scale (Uber, Netflix, DoorDash)
• Visibility: Built-in UI for workflow monitoring, search, and debugging
• Signals & queries: Interact with running workflows without polling

Quick Start

# Install the Python SDK
pip install temporalio

# Start Temporal server (dev mode)
brew install temporal
temporal server start-dev

from temporalio import workflow, activity
from temporalio.client import Client
from temporalio.worker import Worker

@activity.defn
async def say_hello(name: str) -> str:
    return f"Hello, {name}!"

@workflow.defn
class GreetingWorkflow:
    @workflow.run
    async def run(self, name: str) -> str:
        return await workflow.execute_activity(
            say_hello, name, schedule_to_close_timeout=timedelta(seconds=10)
        )
