| * This node implements the Synchronization (AND-Join) workflow pattern. |

| * The Synchronization workflow pattern synchronizes multiple parallel threads of execution |
| * into a single thread of execution. |
| * |
| * Workflow execution continues once all threads of execution that are to be synchronized have |
| * finished executing (exactly once). |
| * |
| * Use Case Example: After the confirmation email has been sent and the shipping process has |
| * been completed, the order can be archived. |
