Manage manually triggered workflows - Data Development| Alibaba Cloud Documentation Center

In a manually triggered workflow, all nodes must be manually triggered, and cannot be scheduled. Therefore, you do not need to specify a parent node or output for a node in a manually triggered workflow.

Create a manually triggered workflow

Go to the DataStudio page.
1. Log on to the DataWorks console.
2. In the left-side navigation pane, click Workspaces.
3. In the top navigation bar, select the region where your workspace resides, find the workspace, and then click Data Analytics in the Actions column.
On the left-side navigation submenu, click the Manually Triggered Workflows icon.
You can click the icon in the lower-left corner to show or hide the left-side navigation submenu.
Right-click Manually Triggered Workflows and select Create Workflow.
In the New business process dialog box, set the Business Name and Description parameters.

Notice The workflow name must be 1 to 128 characters in length and can contain letters, digits, underscores (_), and periods (.). It is not case-sensitive.
Click New.

GUI elements

The following table describes the GUI elements on the configuration tab of a manually triggered workflow.


No.	GUI element	Description
1	Submit	Commit all nodes in the manually triggered workflow.
2	Run	Run all nodes in the manually triggered workflow. Nodes in this workflow do not have dependencies. Therefore, they can be run at the same time.
3	Stop	Stop running nodes.
4	Deploy	Go to the Deploy page. On this page, you can deploy specific or all nodes that are committed but not deployed to the production environment.
5	Go to Operation Center	Go to the Operation Center page.
6	Box	Draw a box to select required nodes to form a node group.
7	Refresh	Refresh the configuration tab of the manually triggered workflow.
8	Auto Layout	Automatically sort the nodes in the manually triggered workflow.
9	Zoom In	Zoom in the directed acyclic graph (DAG).
10	Zoom Out	Zoom out the DAG.
11	Query	Search for a node in the manually triggered workflow.
12	Toggle Full Screen View	Display nodes in the manually triggered workflow in the full screen.
13	Show Engine Information	Show or hide engine information.
14	Workflow Parameters	Set parameters. Workflow parameters have a higher priority than node parameters. If a parameter is set for both the workflow and a node, the parameter that is set for the manually triggered workflow takes effect.
15	Change History	View the operation records of all nodes in the manually triggered workflow.
16	Versions	View the deployment records of all nodes in the manually triggered workflow.

Composition of a manually triggered workflow

Note We recommend that you create no more than 100 nodes in a manually triggered workflow.

A manually triggered workflow can contain a variety of nodes. After you create a manually triggered workflow based on the preceding procedure, you can create nodes in the workflow. For more information, see Manage workflows.

Data Integration
Double-click Data Integration under a manually triggered workflow to view all the data integration nodes in the workflow.

Right-click Data Integration and choose Create > Batch Synchronization to create a batch sync node. For more information, see Batch Sync node.
MaxCompute

Notice The MaxCompute folder appears on the page only after you add a MaxCompute compute engine on the Workspace Management page. For more information, see Configure a workspace.
The MaxCompute compute engine allows you to create data analytics nodes, such as ODPS SQL, SQL Snippet, ODPS Spark, PyODPS 2, ODPS Script, ODPS MR, and PyODPS 2 nodes. You can also create and view tables, resources, and functions.
- Data Analytics
  Click MaxCompute under the manually triggered workflow and right-click Data Analytics to create a data analytics node. For more information, see Create an ODPS SQL node, Create an SQL component node, Create an ODPS Spark node, Create a PyODPS 2 node, Create an ODPS Script node, Create an ODPS MR node, and Create a PyODPS 3 node.
- Table
  Click MaxCompute under the manually triggered workflow and right-click Table to create a table. You can also view all the tables that are created in the current MaxCompute compute engine. For more information, see Create a MaxCompute table.
- Resource
  Click MaxCompute under the manually triggered workflow and right-click Resource to create a resource. You can also view all the resources that are created in the current MaxCompute compute engine. For more information, see Create, reference, and download MaxCompute resources.
- Function
  Click MaxCompute under the manually triggered workflow and right-click Function to create a function. You can also view all the functions that are created in the current MaxCompute compute engine. For more information, see Create a MaxCompute function.
EMR

Notice The EMR folder appears on the page only after you add an E-MapReduce compute engine on the Workspace Management page. For more information, see Configure a workspace.
The E-MapReduce compute engine allows you to create data analytics nodes, such as EMR Hive, EMR MR, EMR Spark SQL, EMR Spark, EMR Shell, EMR Spark Shell, EMR Presto, and EMR Impala nodes. You can also create and view E-MapReduce resources.
- Data Analytics
  Click EMR under the manually triggered workflow and right-click Data Analytics to create a data analytics node. For more information, see Create an EMR Hive node, Create an EMR MR node, Create an EMR Spark SQL node, Create an EMR Spark node, and EMR Presto node.
- Resource
  Click EMR under the manually triggered workflow and right-click Resource to create a resource. You can also view all the resources that are created in the current E-MapReduce compute engine.
- Function
  Click EMR under the manually triggered workflow and right-click Function to create a function. You can also view all the resources that are created in the current E-MapReduce compute engine.
Algorithm
Click the manually triggered workflow and right-click Algorithm to create an algorithm. You can also view all the Machine Learning experiment nodes that are created in the manually triggered workflow. For more information, see Create a Machine Learning (PAI) node.
General
Click the manually triggered workflow and right-click General to create relevant nodes. For more information, see Create a Shell node and Create a zero-load node.
UserDefined
Click the manually triggered workflow and right-click UserDefined to create relevant nodes. For more information, see Create a Data Lake Analytics node and Create an AnalyticDB for MySQL node.
