| 19 | +This example show you how to create workflows in batch mode. After this example run, we will create 10 |
| 20 | +workflows named `workflow:<workflow_num>`, and with 3 tasks named `task:<task_num>-workflow:<workflow_num>` |
| 21 | +in each workflow. Each workflow is linear shape as below, since we set `IS_CHAIN=True` |
| 22 | +
|
| 23 | +task:1-workflow:1 -> task:2-workflow:1 -> task:3-workflow:1 |
