Example Embodiment
[0027] Example one
[0028] Reference figure 1 , Shows a step flow chart of an embodiment of a method for visualizing global task node dependency of the present application, which may specifically include the following steps:
[0029] Step 110: Initiate a task display request; the task display request includes the identifier of the current task node;
[0030] In the embodiment of this application, taking the ODPS platform as an example, when a certain data service is deployed, the data service will be split into a series of tasks and deployed to the ODPS platform. The above tasks are the minimum schedules running on the data platform. Operation unit. However, due to the dependency relationship between the various tasks in the series of tasks, each task can be regarded as a task node, and each task node may have a dependency relationship with one or more task nodes. Such as Figure 1A As shown in the example, the results processed by task nodes 1, 2, and 3 are transmitted down to ta...

[0108] Example two
[0109] Reference figure 2 , Shows a step flow chart of an embodiment of a method for visualizing global task node dependency of the present application, which may specifically include the following steps:
[0110] Step 210: Initiate a task display request; the task display request includes the identifier of the current task node, and the upstream dependency level and the downstream dependency level starting from the current task node;
[0111] In the embodiment of the present invention, the user can set the upstream dependency level and the downstream dependency level to be displayed on the client, and at the same time specify the ID of the current task node, and then send it to the background server through a task display request. The upstream dependency level and the downstream dependency level are both relative to the current task node. such as Figure 1A In task node 6, task nodes 3 and 4 directly associated with task node 6 are the first level upstream dep...

[0122] Example three
[0123] Reference image 3 , Shows a structural block diagram of an embodiment of an apparatus for visualizing a global task node relationship of the present application, which may specifically include the following modules:
[0124] The display request initiating module 310 is configured to initiate a task display request; the task display request includes the identifier of the current task node;
[0125] The recursive search module 320 is configured to recursively search for upstream dependent task nodes and downstream dependent task nodes based on the identification of the current task node in the task display request, starting from the current task node; wherein, in the recursive process, all State data and dependency relationships of current task nodes, upstream dependent task nodes, and downstream dependent task nodes;
[0126] The rendering display module 330 is used to render and display the global relationship tree based on the state data and dependency ...
