Detailed Description
The task scheduling method provided by the embodiment of the application can be applied to electronic equipment such as a server, a server group or a computing center, and the specific type of the electronic equipment is not limited at all.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
In the task scheduling system, the client and the server are connected with each other through a network, the client is provided with the webpage application, the server is provided with the system background of the webpage application, a user can trigger the corresponding function through the webpage application, and the system background executes the function to meet the requirements of the user.
Fig. 1 is a schematic flowchart of a task scheduling method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
and S110, determining a plurality of tasks to be executed according to the execution instruction.
When a user triggers a certain function option in a webpage application of a client, a corresponding execution instruction can be generated, and the execution instruction can comprise generation time, a server address for receiving the execution instruction, option content and the like. The client can send the execution instruction to the corresponding server according to the address. Each execution instruction corresponds to a plurality of tasks in the system background, the corresponding tasks are executed to complete corresponding functions, and after the server receives the execution instructions, the plurality of tasks to be executed can be determined according to option contents in the execution instructions.
For example, when a user clicks the option of "create application" in a development collaboration platform (a web application), the client may generate an execution instruction of the create application, and send the execution instruction of the create application to the server. The server can determine tasks such as creating a code warehouse, restoring a database, pulling a creating tool and the like according to the execution instruction, and complete the function of creating the application by executing the tasks.
Specifically, each task may include a name, execution content, and rollback content of the task, where the execution content and the rollback content are paired, for example, if the execution content of the task of creating the code repository is "create a corresponding code repository according to an identifier input by a user", the rollback content is "delete a created code repository according to an identifier input by a user"; the execution content of the order generating task is 'generate an order', and the rollback content is 'cancel the generated order'.
And S120, executing the tasks and determining the execution state of each task.
For each function, the tasks corresponding to the function have a set execution relationship, and the execution relationship comprises serial execution, parallel execution and mixed execution. For example, the server determines task 1, task 2 and task 3 to be executed according to the execution instruction, wherein when the execution relation among the three tasks is serial, task 1, task 2 and task 3 can be executed in sequence; when the execution relation among the three tasks is parallel, the task 1, the task 2 and the task 3 can be executed simultaneously; when the execution relation between the three tasks is mixed execution, the task 1 and the task 2 are in series, that is, the task 2 is executed after the task 1 is executed, and the task 1 and the task 3 are in parallel, that is, the server can execute the task 1 and the task 3 at the same time.
The server can sequentially execute a plurality of tasks according to a preset execution relation and determine the execution state of each task, wherein when the tasks are not executed or are being executed, the execution state is not finished; when the task is successfully executed, the execution state is successful; when the task fails to execute, the execution state is execution failure.
Specifically, for each task, the server may construct a task model corresponding to the task according to an execution relationship between the task and another task, where the task model may include the task and a tree structure of the task, and the tree structure includes a parent-child relationship and a sibling relationship of the task. Fig. 2 is a schematic diagram of a tree structure provided in the embodiment of the present application, where a task model includes a tree structure of a task 3 and a task 3, and fig. 2 is a tree structure of the task 3. The task 1 and the task 3 are in a serial execution relationship, and the task 1 is executed firstly and then the task 3 is executed during execution, so that the task 1 and the task 3 are in a parent-child relationship, wherein the task 1 is a parent task, and the task 3 is a child task; task 4 and task 3 are also in a serial execution relationship, and when the execution is performed, task 3 is executed first, and then task 4 is executed, so that task 3 and task 4 are also in a parent-child relationship, wherein task 3 is a parent task, and task 4 is a child task; task 2 and task 3 are in parallel execution relationship, and task 2 and task 3 are executed simultaneously during execution, so task 2 and task 3 are in sibling relationship.
When the scheme of the application is actually implemented, the system background can provide a task constructor, then the system background can sequentially input a plurality of tasks to be executed into the task constructor, and the task constructor generates a corresponding tree structure according to the execution relation of the tasks and generates a corresponding task model. The task model may also include, among other things, the name of the task model and the execution model (serial or parallel).
After each task model is constructed, the server can sequentially execute tasks in each task model according to the tree structure of each task model. After a task is executed, the server may determine a corresponding subtask according to the tree structure of the task model, and then execute the subtask until all tasks are executed. When the scheme of the application is actually implemented, the system background can provide a plurality of task executors, and the task executors are responsible for identifying the content of the task model and executing the task according to the execution model of the task.
Specifically, the server may further determine a task queue according to a tree structure of each task model, where the task queue may include an execution order and an execution state of the task model. For each task model, the server can execute the tasks in the task model according to the execution sequence in the task queue and update the execution state of the task model, wherein the execution state of the task model can include enqueued, waiting, executing successfully executing, and executing unsuccessfully.
For example, after the task queue is determined, the execution states of all task models are enqueued, and then the server may execute the tasks in the first task model according to the execution sequence, at this time, the server may update the execution state of the first task model to be in execution, and update the execution state of the second to-be-executed task model to be in wait; after the task execution of the first task model is finished, the server may update the execution state of the first task model to be successful in execution, update the execution state of the second task model to be in execution, update the execution state of the third to-be-executed task model to be in waiting, and then sequentially complete the execution of the tasks in all the task models in the task queue.
When the server determines the execution state of each task, the execution state of each task may be determined according to the execution state of each task model in the task queue. For example, when the execution state of the task model is enqueued, waiting, or executing, the execution state of the corresponding task may be determined to be not executed; when the execution state of the task model is successful, determining the execution state of the corresponding task as successful execution; when the execution state of the task model is an execution failure, the execution state of the corresponding task may be determined as an execution failure.
Specifically, for the execution instruction, it is indicated that the execution of the execution instruction is successful only when all tasks corresponding to the execution instruction are successfully executed, and if any task fails to be executed, it is indicated that the execution of the execution instruction fails, and at this time, the system background needs to rollback all executed tasks to recover the state before the execution of the execution instruction. In order to improve the execution success rate of the execution instruction, the scheme of the application further comprises a retry mechanism, namely when the current task fails to be executed, the server can execute the task again, and if the task fails to be executed again, all executed tasks are rolled back.
In the application, the execution state of the detailed task model can be recorded through the task queue, and then the execution state of the task is determined according to the execution state of the task model, so that in the actual application, a maintainer at a system background can know the detailed progress of each task, and a user can also know the overall progress of the execution instruction.
And S130, notifying the execution progress of the execution command to the client according to the execution state of each task.
The server can determine the execution progress of the execution instruction according to the execution state of each task and send the execution progress to the client. The server may preset a determination period of the execution progress, and then determine and send the execution progress every other period, so that the client displays the execution progress. After the client receives the execution progress, the content of the execution progress can be displayed in the webpage application, so that the user can know that the webpage application processes the operation of the user.
Specifically, when the execution states of the tasks are all successfully executed, the server may determine that the execution progress includes indication information that the execution of the execution instruction is successful; when the execution state of at least one task is not completely executed, the server can determine that the execution progress comprises proportion information of the number of successfully executed tasks to the total number of tasks; when there is an execution status of at least one task as an execution failure, the server may determine that the execution progress includes indication information of the execution failure of the execution instruction.
In the embodiment of the application, the server may determine a plurality of tasks to be executed according to the execution instruction, then execute each task, determine the execution state of each task, and finally notify the execution progress of the execution instruction to the client according to the execution state of each task, where the execution instruction is triggered by the user in the web application of the client. According to the method and the device, the server can determine the execution progress of the execution instruction according to the execution state of each task, and inform the client of the execution progress, so that the client can feed back the processing state in time, and the use experience of a user is improved.
