Summary of the application
In the process of implementing the present disclosure, the inventor finds that, in the prior art, the process rollback is based on manual judgment, and manual operation is performed to rollback, but the technical solution has at least the following problems: a large amount of manual participation is needed, the manpower is wasted, the efficiency is low, and the error rate is high.
Exemplary method
Fig. 1 is a flowchart illustrating a flow rollback method according to an exemplary embodiment of the present disclosure. The embodiment can be applied to an electronic device, as shown in fig. 1, and includes the following steps:
And step 104, in response to that the first node executing in the flow meets the rollback condition, determining a second node corresponding to the rollback operation based on the rollback condition.
The flow in this embodiment includes a plurality of nodes, an execution order exists between the nodes, and the flow may include at least one branch, for example, the flow may include a tree structure; the second node in this embodiment is executed before the first node, that is, the first node can be executed only after the second node needs to be executed in the process, and therefore, when the first node needs to be rolled back, the first node is rolled back to the second node.
And 106, determining at least one third node corresponding to the rollback operation based on the second node.
In some alternative embodiments, the third node may be all nodes that have executed as a result of utilizing the second node and that have executed when the flow is executed to the first node.
And 108, executing a rollback operation on the process according to the second node, so that the process is rolled back to the second node.
In this embodiment, the position of the second node to be returned is already determined, and at this time, returning the execution of the process to the second node can complete the returning operation, thereby implementing automatic returning.
And step 110, re-executing the process from the second node, and updating the execution result data corresponding to the first node, the second node and at least one third node.
After the execution rollback, the previously obtained execution result data of the first node, the second node, and all the third nodes are all invalidated, at this time, the execution result data of the new first node, the new second node, and all the third nodes are obtained based on the result of the re-execution flow, and the new execution result data are updated to the corresponding nodes.
The flow rollback method provided by the above embodiment of the present disclosure obtains execution state information of a flow; in response to that a first node executing in the process meets a rollback condition, determining a second node corresponding to rollback operation based on the rollback condition; determining at least one third node corresponding to the rollback operation based on the second node; executing a rollback operation on the process according to the second node, and enabling the process to roll back to the second node; re-executing the flow from the second node, and updating execution result data corresponding to the first node, the second node and at least one third node; the embodiment of the disclosure realizes automatic rollback according to the set rollback condition without manual operation, improves the rollback efficiency, avoids redundant data from being generated, and can directly respond to data change; the nodes needing rollback and re-execution in the whole process are all executed by determining the second node starting rollback and the third node needing re-execution, so that the problem of final result errors caused by missing nodes is avoided.
In some alternative embodiments, step 104 may include:
responding to the fact that execution result data of a first node executing in the process meets a preset condition, and determining a second node retreating to according to configuration information of the current node; or the like, or, alternatively,
in response to receiving the fallback request, a second node to fallback to is determined according to the fallback request.
Two fallback conditions are proposed in this embodiment: when execution result data of a first node meets a preset condition, determining a second node according to rollback information configured in the first node; another is according to an external request, for example, when executing to a first node, there is data change in the executed flow node, and at this time, a second node that needs to be fallback to may be determined according to the fallback request.
In some alternative embodiments, step 106 may include:
acquiring all nodes passing from a second node to a first node in a flow as at least one third node; and/or the presence of a gas in the gas,
and acquiring all executed nodes of the second node in all branches corresponding to the flow as at least one third node.
Optionally, the second node may be directly connected to the first node, that is, the first node is directly executed after the second node is executed, but the second node may include other branches (in addition to being connected to the first node), where a parent node (second node) in the tree structure corresponds to at least two child nodes (one of the child nodes is the first node), and at this time, an executed node corresponding to the other branch is a third node; or, the second node is indirectly connected to the first node, that is, the second node is connected to the first node through at least one intermediate node, at this time, the intermediate nodes are third nodes, and at this time, the second node may also include other branches, and at this time, executed nodes corresponding to the other branches are also third nodes.
Fig. 2 is a flowchart illustrating a flowchart rollback method according to another exemplary embodiment of the present disclosure. The embodiment can be applied to an electronic device, as shown in fig. 2, and includes the following steps:
And step 104, in response to that the first node executing in the flow meets the rollback condition, determining a second node corresponding to the rollback operation based on the rollback condition.
And 106, determining at least one third node corresponding to the rollback operation based on the second node.
And 108, executing a rollback operation on the process according to the second node, so that the process is rolled back to the second node.
And step 110, re-executing the process from the second node, and updating the execution result data corresponding to the first node, the second node and at least one third node.
In this embodiment, since it is determined that rollback needs to be executed and nodes below the second node are re-executed, in order to improve the efficiency of process flow processing and avoid generating redundant data, the present embodiment needs to suspend the execution of the nodes in the process flow after determining the nodes (including the first node, the second node, and all the third nodes) that need to be rolled back.
As shown in fig. 3, based on the embodiment shown in fig. 1, step 110 may include the following steps:
The process execution task comprises executing a first node, a second node and at least one third node.
And step 1104, asynchronously executing the flow execution task.
The asynchronous execution flow executes the task, can check the current execution progress in real time, and avoids the defect that a user cannot know the task execution progress in the waiting process.
After executing the rollback operation, the current process of the flow is executed to the second node, and nodes below the second node need to be re-executed.
In some optional embodiments, in the embodiment shown in fig. 3, before step 1084, the method may further include:
judging whether the flow meets the execution condition, if so, asynchronously executing the flow to execute the task; otherwise, the execution of the flow is ended.
The embodiment mainly aims at the emergency situation in the process of executing the flow, for example, the flow is determined to terminate the execution due to data or user factors, at this time, the flow is not executed any more, that is, the flow does not meet the execution condition; the process execution task is executed asynchronously only if the process needs to continue execution.
As shown in fig. 4, based on the embodiment shown in fig. 1, step 110 may further include the following steps:
The process execution task comprises executing a first node, a second node and at least one third node.
And 1104, executing the flow execution tasks in the sequence from the second node to the first node and the at least one third node.
In this embodiment, in order to more intuitively view the task execution progress at the front end in the asynchronous execution process, before the asynchronous execution process executes the task, the task completion degree corresponding to each node is determined according to the number of nodes included in the process execution task, for example, when the process execution task includes 5 nodes, the task completion degree advances by 20% every time one node is executed, that is, when the second node is executed, the front end displays the task completion degree as 20%, and when a third node is executed again, the front end displays the task completion degree as 40%.
Optionally, in the embodiment provided in fig. 4, while the step 1104 executes the flow execution task, the step may further include:
and acquiring and displaying the task completion degree of the flow execution task on the front-end page through the query interface.
In the embodiment, the task completion degree of the flow execution task in the execution process is synchronously displayed to the front-end page through the query interface so as to be checked by the user, and the problem that the task completion degree cannot be checked by the user is avoided.
Fig. 5 is a flowchart illustrating a flowchart rollback method according to another exemplary embodiment of the present disclosure. The embodiment can be applied to an electronic device, as shown in fig. 5, and includes the following steps:
And step 104, in response to that the first node executing in the flow meets the rollback condition, determining a second node corresponding to the rollback operation based on the rollback condition.
And 106, determining at least one third node corresponding to the rollback operation based on the second node.
And 108, executing a rollback operation on the process according to the second node, so that the process is rolled back to the second node.
And step 110, re-executing the process from the second node, and updating the execution result data corresponding to the first node, the second node and at least one third node.
And step 512, recording rollback operation and flow execution tasks.
In this embodiment, after the rollback operation and the flow execution task are executed, in order to summarize problems that easily occur in the flow or the number of times of flow rollback and the like later, the rollback operation and the flow execution task are recorded, and when similar problems occur in subsequent flows, the stored records may be referred to for processing, or a certain type of flow often occurs to be summarized, and the type of flow may be modified by referring to the records, so as to improve the flow executability.
