"""
This example show you how to create workflows in batch mode.

After this example run, we will create 10 workflows named `workflow:<workflow_num>`, and with 3 tasks
named `task:<task_num>-workflow:<workflow_num>` in each workflow. Task shape as below

task:1-workflow:1 -> task:2-workflow:1 -> task:3-workflow:1

Each workflow is linear since we set `IS_CHAIN=True`, you could change task to parallel by set it to `False`.
