How to spawn a Workflow Execution in Python

To start a Workflow Execution in python, use either the start_workflow() or execute_workflow() asynchronous methods in the Client.

The following code example starts a Workflow and returns its handle.

async def main():
    client = await Client.connect("127.0.0.1:7233", namespace="your-custom-namespace")

    handle = await client.start_workflow(
        "your-workflow-name",
        "some arg",
        id="your-workflow-id",
        task_queue="your-task-queue",
    )

The following code example starts a Workflow and waits for completion.

async def main():
    client = await Client.connect("127.0.0.1:7233", namespace="your-custom-namespace")

    handle = await client.execute_workflow(
        "your-workflow-name",
        "some arg",
        id="your-workflow-id",
        task_queue="your-task-queue",
    )
