    Data Management:UpdateTaskFlowEdges

    Last Updated:Nov 28, 2024

    Updates the start node and end node of multiple edges at a time for a task flow.

    Operation description

    The edges can be updated only when the following conditions are met:

    1. The specified edge exists in the directed acyclic graph (DAG) of the task flow specified by DagId.
    2. The specified edge nodes exist in the DAG of the task flow specified by DagId.
    3. After the update, rings do not exist in the DAG.

    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.
