Sleep Workflow Sample

This sample workflow demonstrates how to use the workflow.Sleep function in Cadence workflows. The sleep functionality allows workflows to pause execution for a specified duration before continuing with subsequent activities.

Sample Description

The sample workflow:

• Takes a sleep duration as input parameter
• Uses workflow.Sleep to pause workflow execution for the specified duration
• Executes a main activity after the sleep period completes
• Demonstrates proper error handling for sleep operations
• Shows how to configure activity options for post-sleep activities

The workflow is useful for scenarios where you need to:

• Implement delays or timeouts in workflow logic
• Wait for external events or conditions
• Implement retry mechanisms with exponential backoff
• Create scheduled or periodic workflows

Key Components

• Workflow: sleepWorkflow demonstrates the sleep functionality with activity execution
• Activity: mainSleepActivity is executed after the sleep period
• Sleep Duration: Configurable duration (default: 30 seconds) passed as workflow input
• Test: Includes unit tests to verify sleep and activity execution

Steps to Run Sample

1. You need a cadence service running. See details in cmd/samples/README.md

2. Run the following command to start the worker:

   ./bin/sleep -m worker
   

3. Run the following command to execute the workflow:

   ./bin/sleep -m trigger
