Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The informatization of medical services is an international development trend. With the rapid development of information technology, more and more hospitals in China are accelerating to implement overall construction based on an information platform and the like so as to improve the service level and the core competitiveness of the hospitals. The premise of informatization is to establish a data warehouse, and the scheduling of the task of data extraction is an important part in the process.
At present, data extraction tasks are mainly divided into real-time scheduling and timing scheduling, the whole process of data extraction and arrangement is divided into a plurality of data processing subtasks, a large task is firstly established, the plurality of subtasks are placed into the large task, the front-back sequence of the subtasks is configured in advance, and the like, a determined flow is formed, and the tasks are executed in sequence according to the preset flow. However, the task driving mode is relatively fixed and rigid, high coupling exists between the whole task and the subtasks, and the task driving mode is not flexible to schedule.
Meanwhile, the outer layer of the large task occupies one thread, and the overall resource allocation is influenced; if the thread of the outer layer large task has a problem, all tasks are affected. The sequence of the subtasks is fixed, and the drive of the subsequent subtasks is not changed in time according to the execution result of the previous subtask, so that the change and the adjustment are not easy.
Disclosure of Invention
In order to solve the problems, the invention provides a method, a system, a storage medium and equipment for driving tasks by log messages.
According to some embodiments, the invention adopts the following technical scheme:

executing the subtasks, and putting the generated logs into a queue, wherein the logs comprise current subtask information, result information of subtask execution and possible next-step driving task information;
if the result information of the subtask execution of the current log is successful, inserting the log information of the subtask into a database, and executing the subtask corresponding to the next possible driving task information until the whole task is completed;
if the result information of the subtask execution of the current log is failure, the log information in the queue cache is inserted into a database for solidification, whether the subtask information corresponding to the log is a key task node is judged, and if yes, all tasks are ended; and if not, driving the next subtask, and removing the related log information from the queue after the processing is finished.
As an alternative, the above-described method steps are performed cyclically.
As an alternative implementation mode, a linked list mechanism is formed among all subtasks belonging to the same large task, and the subtasks carry out the next task driving according to executed log information, namely whether each task is executed or not is related to the front task of each task.
As an alternative embodiment, a queue is created for each large task, and the queue collects and processes all tasks in a workflow.
As an alternative, each subtask includes information about the task to be executed by the subtask itself, information about the next possible driving task, and a relevant determination condition for triggering the driving task.
As an alternative implementation, if there are multiple logs, the logs are sorted in time in a queue and processed in order.
As an alternative embodiment, if there are a plurality of subtasks to be executed simultaneously, the log information generated by the respective subtasks is inserted into the queue at the same time.
As an alternative implementation manner, if the result information of the sub-task execution of the current log is failure, the reminding task is driven at the same time to remind that the corresponding sub-task execution fails.
A log message driven task system, comprising:
the log queue building module is configured to put logs generated by executing the subtasks into a queue, wherein the logs comprise current subtask information, result information of subtask execution and possible next-step driving task information;

A terminal device comprising a processor and a computer readable storage medium, the processor being configured to implement instructions; the computer readable storage medium stores instructions adapted to be loaded by a processor and to perform the steps of the log message driven task method.
Compared with the prior art, the invention has the beneficial effects that:
the invention breaks through the form of the prior fixed task flow before the original task is executed, and drives the next task to be executed through the log of the previous task node, thereby more reasonably finishing the work of data extraction; the subtasks can be finished in real time, and the threads are released in real time. The bus program is not worried about suddenly dropping to influence the execution of all the subtasks, and the scheduling execution of the tasks is more stable.
The invention cancels the outer layer large task containing all subtasks, reduces the occupation of the thread to system resources, reduces the high coupling between tasks by adopting the log driving task, improves the stability of task scheduling, and does not interrupt the execution of the whole task due to the failure of the total task thread or the single subtask thread.
The execution sequence of each subtask can be flexibly changed, and compared with the original fixed execution flow, the method realizes flexible selection and adjustment of the next execution task by the log-driven task.
The invention does not need to solidify the whole task scheduling process before task execution, reduces mutual coupling, has higher task scheduling flexibility, and supports more various and complex scheduling conditions.
