Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first aspect, embodiments of the present invention provide a method for implementing a timing task, which can effectively improve the efficiency of modifying the timing task.
As shown in fig. 1, a method for implementing a timing task according to an embodiment of the present invention includes:
s11, synchronizing a timing task to be monitored once from a task library at intervals of preset time length to form a timing task list, wherein the timing task in the task library is editable by a user and does not belong to a system file;
optionally, the task library in the embodiment of the present invention may be any file and/or database that can record a timed task and is established by a user, for example, a text file, a relational database MySQL, and the like. The task library is established by a user, does not belong to the system file, and is not necessarily restricted by the management of the system file.
Optionally, one or more timing tasks may be recorded in the task library, and each timing task may have its own identifier and a corresponding time node.
In this step, the synchronization operation is performed once every preset time interval, optionally, the preset time intervals of the synchronization operations may be equal or different, for example, in an embodiment of the present invention, the preset time interval may be 1 minute, in another embodiment of the present invention, the preset time interval may also be 1 minute for the first time interval, and 3 minutes for the second time interval.
And S12, performing timing monitoring on the timing task according to the timing task recorded in the latest synchronous timing task list and the corresponding execution time.
In this step, the timed task list can periodically synchronize the latest version data in the task library and be read by the timing system in time, so as to perform timing monitoring on the timed task according to the timed task and the corresponding execution time recorded in the timed task list. Optionally, in an embodiment of the present invention, if the data amount in the task library is huge and the execution times of many tasks are far apart, each time data synchronization is performed, only timing tasks before a preset time node may be synchronized, for example, only timing tasks within one hour are synchronized.
The implementation method of the timing task provided by the embodiment of the invention can synchronize the timing task to be monitored once from the task library at intervals of preset duration to form a timing task list, and perform timing monitoring on the timing task according to the timing task and the corresponding execution time recorded in the latest synchronized timing task list. The timed tasks in the task library are editable by the user, and the task library does not belong to a system file, so that the user can conveniently edit the timed tasks in the task library, and the edited timed tasks are timely updated to the timed task list through synchronous operation of preset time duration at intervals, so that the modification of the timed tasks is timely effective, and the modification operation efficiency of the timed tasks is effectively improved.
Optionally, when the timing tasks are numerous, in order to further improve the operation efficiency of the monitoring program and improve the disaster tolerance performance of the monitoring program, in an embodiment of the present invention, in step S11, synchronizing the timing tasks to be monitored from the task library at a time every preset time interval may specifically include:
and each program operation unit in the at least two program operation units synchronizes timing tasks which need to be monitored respectively once from the task library at intervals of preset time length, wherein the timing tasks monitored by each program operation unit are not repeated.
Optionally, in this embodiment, the program running unit may include a relatively independent program structure such as a docker (container) or a process. Each program operation unit can simultaneously or sequentially synchronize data from the task library. The task library can record which program running unit takes over and monitors each timing task. The preset time intervals for performing data synchronization by each program operation unit may be equal or different, and this is not limited in the embodiment of the present invention. Different program operation units can be operated on the same server or different servers to form a distributed system.
For example, at time T1, five timing tasks of task1, task2, task3, task4 and task5 exist in the task library in one embodiment of the invention. The program operation unit P1 synchronizes tasks task1, task2 and task3 in the task library to the timing program list L1 in the program operation unit P1, and the program operation unit P2 synchronizes tasks task4 and task5 in the task library to the timing program list L2 in the program operation unit P2. At time T2, the user has modified the task library, adding timed tasks task6, task 7. At time T3, the program running unit P1 synchronizes tasks task1, task2, task3, and task6 in the task library to the timer program list L1 in the program running unit P1. At time T4, the program operation unit P2 synchronizes tasks task4, task5, and task7 in the task library to the timer program list L2 in the program operation unit P2.
Further, in order to orderly perform the timing tasks among the program operation units when the timing tasks are monitored by at least two program operation units, in an embodiment of the present invention, the step S12 may specifically include, according to the timing tasks and the corresponding execution times recorded in the latest synchronized timing task list, performing timing monitoring on the timing tasks:
each program running unit in the at least two program running units competes for the mutual exclusion lock;
and the program operating units competing the mutual exclusion lock perform timing monitoring on the timing task according to the timing task and the corresponding execution time recorded in the latest synchronous timing task list.
Specifically, the task execution flow of the distributed timed task monitoring may be as shown in fig. 2, and the program architecture of the distributed timed task monitoring may be as shown in fig. 3. With reference to fig. 2 and fig. 3, since each timing task may involve read/write operations of the memory and/or the database, in order to avoid conflicts between the read/write operations of different program operating units (e.g., docker) on the memory and/or the database, in an embodiment of the present invention, a mutual exclusion lock may be applied to the timing task before the timing tasks monitored by the different program operating units are executed, and each program operating unit may allow the timing task to be executed only when competing for the mutual exclusion lock. Otherwise, if a program running unit does not compete for the mutex this time, the timing task cannot be executed this time. The program running unit can continue to compete for the mutex lock at the next time until the mutex lock is competed, and then the timed task is executed.
In the embodiment, different timing tasks in the task library are respectively monitored by the plurality of program operation units, and the program operation units cooperate with each other, so that the monitoring efficiency is greatly improved. Moreover, in other embodiments of the present invention, when some program running units have running faults due to various reasons or when the execution task is arranged additionally, the monitoring timing task can be transferred to other program running units for continuous monitoring, thereby effectively improving the disaster tolerance performance of task monitoring.
Optionally, in an embodiment of the present invention, the method for implementing the timing task provided by the embodiment of the present invention may further include:
when the first program operation unit has a fault during operation, feeding back the fault condition to the task library;
and migrating the timing tasks which are executed and/or not executed in the first program running unit to other program running units by carrying out synchronous operation on the task library at intervals of preset time length.
Optionally, in another embodiment of the present invention, the method for implementing the timing task provided in the embodiment of the present invention may further include:
when the first program running unit needs to be closed, feeding a closing instruction back to the task library;
and migrating the timing task which is not executed in the first program running unit to other program running units by carrying out synchronous operation on the task library at intervals of preset time length.
The above embodiments illustrate how effective monitoring of timed tasks can be achieved. It can be understood that, while monitoring the timing task is realized, the implementation method of the timing task provided by the embodiment of the invention also allows a user to edit and modify the timing task at any time, and can enable the editing and modifying to take effect in time, thereby effectively improving the modification operation efficiency of the timing task.
For example, optionally, in an embodiment of the present invention, the method for implementing the timing task provided in the embodiment of the present invention may further include:
receiving an editing operation on the task library, wherein the editing operation comprises at least one of the following: adding a timing task, deleting the timing task and modifying the timing task;
