Core Application

Use the essential components of a Temporal Application (Workflows, Activities, and Workers) to build and run a Temporal application.

• Develop a Basic Workflow
• Develop a Basic Activity
• Start an Activity Execution
• Run Worker Processes

Temporal Client

Connect to a Temporal Service and start a Workflow Execution.

• Connect to Development Temporal Service
• Connect a Temporal Client to a Temporal Service
• Connect to Temporal Cloud
• Start a Workflow Execution

Python SDK Sandbox

Use third-party Python modules without non-deterministic behavior.

Python SDK sync vs. async implementations

Implement synchronous or asynchronous Activities.

Testing

Set up the testing suite and test Workflows and Activities.

• Test Frameworks
• Testing Activities
• Testing Workflows
• How to Replay a Workflow Execution

Failure Detection

Explore how your application can detect failures using timeouts and automatically attempt to mitigate them with retries.

• Workflow Timeouts
• Set Activity Timeouts
• Heartbeat an Activity

Workflow Message Passing

Send messages to and read the state of Workflow Executions.

• Develop with Signals
• Develop with Queries
• Develop with Updates
• What is a Dynamic Handler

Interrupt a Workflow

Interrupt a Workflow Execution with a Cancel or Terminate action.

• Cancel a Workflow
• Terminate a Workflow
• Cancel an Activity from a Workflow

Asynchronous Activity Completion

Complete Activities asynchronously.

• Asynchronously Complete an Activity

Versioning

Change Workflow Definitions without causing non-deterministic behavior in current long-running Workflows.

• Introduction to Versioning
• How to Use the Patching API
• How to Use Worker Versioning

Observability

Configure and use the Temporal Observability APIs.

• Emit Metrics
• Set up tracing
• Log from a Workflow
• Use Visibility APIs

Debugging

Explore various ways to debug your application.

• Debugging

Schedules

Run Workflows on a schedule and delay the start of a Workflow.

• Schedule a Workflow
• Temporal Cron Jobs
• Start Delay

Data Encryption

Use compression, encryption, and other data handling by implementing custom converters and codecs.

• Custom Payload Codec
• Payload Conversion

Durable Timers

Use Timers to make a Workflow Execution pause or "sleep" for seconds, minutes, days, months, or years.

• Sleep

Child Workflows

Explore how to spawn a Child Workflow Execution and handle Child Workflow Events.

• Start a Child Workflow Execution

Continue-As-New

Continue the Workflow Execution with a new Workflow Execution using the same Workflow ID.
