OBS Manager

Constraints

This function depends on OBS.

Function

The OBS Manager node is used to move or copy files from an OBS bucket to a specified directory.

Parameters

Table 1, Table 2, and Table 3 describe the parameters of the OBS Managernode node.

Table 1 Parameters of OBS Manager 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 (>).

Operation Type

Yes

Operations that can be performed on the node.

  • Move File: moves a source file or directory to a new directory.
  • Copy File: copies the source file or directory.
  • Rename File: renames the last level of the directory or file.

    For example, you can rename the directory obs://test/a/b/c/ as obs://test/a/b/d/, and rename the file obs://test/a/b/hello.txt as obs://test/a/b/bye.txt.

  • Monitor File: checks whether a file or directory exists. If the file or directory exists, the node is executed successfully. Otherwise, the node fails to be executed.

    If you want the job to be handled in different ways based on whether the file or directory exists, you can set an IF condition based on the execution status of the node. For details, see IF Statements.

Source File or Directory

Yes

OBS file or directory to be managed in the OBS bucket.

Target Directory

Yes

Directory for storing OBS files to be moved or copied from the OBS bucket.

File Filter

No

Wildcard for file filtering. Only the files that meet the filtering condition can be moved or copied. If this parameter is not specified, all source files are moved by default. For example, when you enter *.csv, files in this format will be moved or copied.
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.
