DIS Stream

Functions

The DIS Stream node is used to query the status of a DIS stream. If the DIS stream is normal, you can perform other nodes. If the DIS stream is abnormal, the DIS Stream node will send an error message and exit. If you want to perform other nodes, you must set Failure policy to Proceed to the next node. For details about how to set Failure policy, see Table 2.

Parameters

Table 1 and Table 2 describe the parameters of the DIS Stream node.

Table 1 Parameters of DIS Stream nodes

Parameter

Mandatory

Description

Node Name

Yes

Name of the node. Must consist of 1 to 128 characters and contain only letters, digits, underscores (_), hyphens (-), slashes (/), less-than signs (<), and greater-than signs (>).

Stream Name

Yes

Select or enter the DIS stream to be queried. When entering the stream name, you can reference job parameters and use the EL expression (for details, see Expression Overview).

To create a DIS stream, you can use either of the following methods:
  • Click . On the Stream Management page of DLF, create a DIS stream.
  • Go to the DIS console to create a DIS stream.
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 not be retried and is set to the failed state.

Retry upon Failure

Yes

Indicates whether to re-execute a node task if its execution fails. Possible values:

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

If Timeout Interval is configured for the node, the node will not be executed again after the execution times out. Instead, the node is set to the failure state.

Failure Policy

Yes

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

  • End the current job execution plan
  • Go to the next job
  • Suspend the current job execution plan
  • Suspend execution plans of the current and subsequent nodes
