DIS Client

Functions

The DIS Client node is used to send messages to a DIS stream.

You can learn more about how to use the DIS Client node in Scheduling Jobs Across Workspaces.

Parameters

Table 1 describes the parameters of the DIS Client node.

Table 1 Parameters of DIS Client nodes

Parameter

Mandatory

Description

Node Name

Yes

Name of a node. The name must contain 1 to 128 characters, including only letters, numbers, underscores (_), hyphens (-), slashes (/), less-than signs (<), and greater-than signs (>).

Using DIS Connection

No

If DIS streams are used, messages can be sent to the DIS streams of another account. Otherwise, messages can be sent only to streams in all regions of the current account.

DIS Connection

No

This parameter is mandatory only when Using DIS Connection is set to Yes.

Before setting this parameter, ensure that you have created a DIS connection in the Management Center by referring to Creating Data Connections.

This parameter is not required when Using DIS Connection is set to No.

Region

No

Region that the target DIS stream belongs to. The DIS Client node is used to send messages to the target DIS stream.

Stream Name

Yes

DIS stream to which messages will be sent. You can enter a stream address or select a stream.

Sent Data

Yes

Text sent to the DIS stream. You can directly enter text or click to use the EL expression.

Related Job

No

Select batch or real-time processing jobs. You can select a maximum of 10 jobs.

This parameter allows you to switch to the monitoring page of the selected jobs when they start running. After selecting a job, click Monitor. On the Monitory Job page, select the DIS Client node and click View Related Job on the lower part of the page. In the View Related Job dialog box, click View in the Operation column of a job to view the details about the job.
Table 2 Advanced parameters

Parameter

Mandatory

Description

Max. Node Execution Duration

Yes

Execution timeout interval for the node. If retry is configured and the execution is not complete within the timeout interval, the node will be executed again.

Retry upon Failure

Yes

Whether to re-execute a node if it fails to be executed. Possible values:

  • Yes: The node will be re-executed, and the following parameters must be configured:
    • Retry upon Timeout
    • Maximum Retries
    • Retry Interval (seconds)
  • No: The node will not be re-executed. This is the default setting.
    NOTE:

    If retry is configured for a job node and the timeout duration is configured, the system allows you to retry a node when the node execution times out.

    If a node is not re-executed when it fails upon timeout, you can go to the Default Configuration page to modify this policy.

    Retry upon Timeout is displayed only when Retry upon Failure is set to Yes.

Policy for Handling Subsequent Nodes If the Current Node Fails

Yes

Operation that will be performed if the node fails to be executed. Possible values:

  • Suspend execution plans of the subsequent nodes: stops running subsequent nodes. The job instance status is Failed.
  • End the current job execution plan: stops running the current job. The job instance status is Failed.
  • Go to the next node: ignores the execution failure of the current node. The job instance status is Failure ignored.
  • Suspend the current job execution plan: If the current job instance is in abnormal state, the subsequent nodes of this node and the subsequent job instances that depend on the current job are in waiting state.

Enable Dry Run

No

If you select this option, the node will not be executed, and a success message will be returned.

Task Groups

No

Select a task group. If you select a task group, you can control the maximum number of concurrent nodes in the task group in a fine-grained manner in scenarios where a job contains multiple nodes, a data patching task is ongoing, or a job is rerunning.
