UpdateTaskFlowSchedule - Data Management - Alibaba Cloud Documentation Center

Updates the scheduling properties for a task flow.

Operation description

You can call this operation to update the scheduling properties for a task flow in the editing state. You can configure a timed scheduling task flow or an event scheduling task flow. When you configure a timed scheduling task flow, you can choose from one-time scheduling or periodic scheduling. When you configure an event scheduling task flow, you can subscribe to task flows or task flow nodes.****
After you update the scheduling properties, you need to publish and deploy the task flow again. The new task flow instance will run based on the updated scheduling properties.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Note about scheduling configuration parameters

When you configure a timed scheduling task flow, you can choose from one-time scheduling or periodic scheduling.

The following parameters are required:

ScheduleSwitch: True
TriggerType: Cron
CronBeginDate
CronEndDate
CronStr
CronType
ScheduleParam: The task can be run by day, week, month, or only once.

The following section provides examples:

Scheduling by day:

{
    "triggerType":"0",
    "dateTime":"00:00"
}

Scheduling by week: "1" for Sunday, "2" for Monday, ..., and "7" for Saturday.

{
    "triggerType":"0",
    "dateWeek":[
        "1",
        "5"
    ],
    "weekTime":"00:00"
}

Scheduling by month:

{
    "triggerType":"0",
    "dateMonth":"1",

}

Scheduling once:

{
    "triggerType":"1",
    "specificTime":"2022-09-02 00:00"
}

Parameter description

CronStr: CronStr defines how a task flow is scheduled.
CronBeginDate and CronEndDate: For periodic scheduling, CronBeginDate, CronEndDate, and CronStr together define task flow scheduling. If the time specified by CronStr is within the time range between CronBeginDate and CronEndDate, the task is triggered.
CronType: This is used for verification. Enter a value based on the scheduling cycle specified by CronStr.
ScheduleParam: Enter a value based on the scheduling configuration specified by CronStr.

Event Scheduling (automatically triggered across task flows)

The following parameters are required:

ScheduleSwitch: True
TriggerType: Event
ScheduleParam

The following section provides examples:

    "deps":[ // The subscription configurations for task flows and task nodes.
        {
            "eventType":1, // The type of the subscription. The value 0 indicates subscription to task flows. The value 1 indicates subscription to task nodes.
            "lisDagId":12345, // The task flow to which the subscribed node belongs.
            "lisNodeId":2134 // The ID of the node to which you subscribe.
        },
        {
