Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The timed task scheduling method or the timed task processing method provided by the application can be applied to the application environment shown in fig. 1. The main control end 110 communicates with a plurality of scheduling ends 120 through a network, the scheduling ends 120 communicate with a plurality of different execution servers 130 through the network, and the main control end 110, the scheduling ends 120 and the execution servers 130 form a distributed stateless cluster architecture system. The main control terminal 110 reads the operation cycle of each timing task in the database, determines the current target timing task, when the estimated running time of the target timing task is smaller than the preset time index value and no dependent locking exists, sending the metadata of the target timing task to a task queue of a scheduling end corresponding to the running mode of the target timing task, inquiring the task queue at every moment by the scheduling end, when the metadata of the target timing task is inquired from the task queue, the scheduling end calls the execution server 130 to execute the target timing task according to the metadata, so that the scheduling of the timing task and the execution of the timing task are decoupled by using the task queue, the processing work of the timing task among multiple servers and multiple systems is realized, the processing of the timing task is not affected by the performance of the single machine, and the generation of performance bottleneck and the reduction of the execution accuracy and frequency of the timing task are effectively avoided. The main control end 110, the dispatching end 120 and the execution server 130 can be implemented by independent servers or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, a method for scheduling a timed task is provided, which is described by taking the method as an example applied to the master control end in fig. 1, and includes the following steps:
step S210: and reading the running period of each timing task in the database, and determining a target timing task from each timing task according to the running period.
In this step, the main control end can start a concurrent process every minute, and the running period of each timing task in the database is read through the concurrent process, so that the target timing task which needs to run at the current moment is determined according to the running period of each timing task in the database;
specifically, the main control end may store the operation period of each timing task in the database in advance, where the definition mode of the operation period of the timing task may adopt an expression supporting Linux crossbar, so as to implement seamless migration of the timing task supported and deployed in the Linux crossbar.
Step S220: and comparing the estimated running time of the target timing task with a preset time index value, and judging whether the target timing task is dependent on locking.
In this step, the preset time length index value may include a maximum running time length of the timing task, which is set by the user, of the service system by default, and a time interval of a running period of the timing task; the dependency locking means that when the running state of other timing tasks having a dependency relationship with the target timing task is in running, the target timing task has dependency locking;
because the timing tasks are periodically operated, if a certain timing task is started in the previous period and is not operated, the timing task is executed again in the current period, the same timing task is overlapped and operated at different time points, so that the front and back congestion of the timing task is often caused, and the task accumulation pressure is generated on a service system; therefore, after the target timing task needing to be operated at the current moment is determined, the main control end obtains the estimated operation time of the target timing task from the metadata of the target timing task, and the estimated operation time is compared with the preset duration index value, so that the overlapping operation of the timing tasks is effectively avoided, and the accumulation of the task amount is avoided. Meanwhile, the main control end judges whether the target timing task is dependent on locking or not, so that some tasks with sequential execution can be mutually restricted, the design of relevance mutual exclusion between the timing task and the timing task is realized, and the problem of singleness of the timing task is effectively solved.
Step S230: and when the estimated running time of the target timing task is smaller than the preset time index value and no dependency locking exists, determining the running mode of the target timing task.
The timing task operation mode comprises two types, one is that the timing task is triggered to be executed by the WEB application through calling the WEB application interface, and the other is that the timing task is executed by executing the relevant program code on the server where the WEB application is located. When the estimated running time of the target timing task is smaller than a preset time index value and no dependent locking exists, the target timing task meets the running condition, and the main control end can read the metadata of the target timing task and determine the running mode of the target timing task; when the estimated running time of the target timing task is greater than the preset time index value or the target timing task is dependent on locking, the target timing task is considered to be not in accordance with the running condition, and the main control end discards the running of the target timing task.
Step S240: sending the metadata of the target timing task to a task queue of a scheduling end corresponding to the running mode; and the metadata of the target timing task is used for indicating the scheduling end to call the execution server to execute the target timing task according to the metadata.
The execution server is a server where WEB applications which actually complete the timing task function are located; corresponding to different operation modes, the scheduling end is also divided into two scheduling ends with different classifications; specifically, after the operation mode of the target timing task is determined, the main control end sends metadata of the target timing task to a task queue of a scheduling end corresponding to the operation mode, the scheduling end inquires the task queue in real time, and after the scheduling end inquires the metadata of the target timing task in the task queue, an execution server where the WEB application is located is called to execute the target timing task according to the metadata.
In the timing task scheduling method, the current target timing task is determined by reading the running period of each timing task in the database, when the estimated running time of the target timing task is smaller than the preset time index value and no dependent locking exists, sending the metadata of the target timing task to a task queue of a scheduling end corresponding to the running mode of the target timing task, the timing task is dispatched to different dispatching ends, the dispatching end calls an execution server to execute a target timing task, the dispatching of the timing task and the execution of the timing task are decoupled by utilizing a task queue, the processing work of the timing task among multiple servers and multiple systems is realized, the processing of the timing task is not influenced by the performance of a single machine, the generation of performance bottleneck and the reduction of the execution accuracy and frequency of the timing task are effectively avoided, and the expansion and contraction capacity of a scheduling end can be increased or reduced according to the performance requirement; meanwhile, the estimated running time of the target timing task is compared with the preset time index value, and whether the target timing task is dependent and locked or not is judged, so that the congestion problem before and after the running of the timing task is effectively solved, the design of running relevance mutual exclusion among different timing tasks can be realized, and the problem of singleness of the timing task is solved.
In one embodiment, the step of determining whether there is a dependent lock on the target timed task comprises: reading metadata of the target timing task, and determining a first task identifier and a dependency state of a dependent task of the target timing task from the metadata; reading the running state of the timing task corresponding to the first task identifier; and if the running state is not matched with the dependency state, judging that the target timing task has dependency locking.
The dependency locking means that when the running state of other timing tasks having a dependency relationship with the target timing task is not in the dependency state, the target timing task has dependency locking, for example, assuming that the timing task a has a dependency relationship with the timing task B, the timing task a needs to run in the running end state of the timing task B, that is, the dependent task of the timing task a is the timing task B, the dependency state is non-running, when the main control end determines the timing task a as the target timing task, the main control end obtains the identifier of the timing task B having a dependency relationship with the timing task a from the metadata of the timing task a and determines the last running state of the timing task B according to the identifier, if the last running state of the timing task B is non-running, the running state of the timing task B matches with the dependency state, determining that the timing task A is independent of locking; and if the last running state of the timing task B is running, the running state of the timing task B is not matched with the dependency state, and the timing task A is determined to have dependency locking. In this embodiment, the main control end determines a task identifier of a related timing task from metadata of a target timing task, obtains a latest running state of the timing task through the task identifier, and determines that the target timing task has dependency locking when the latest running state of the timing task is in running; by carrying out dependency judgment on the target timing task and the timing task having a dependency relationship with the target timing task, mutual restriction of the timing tasks with sequential execution is realized, the design of running association mutual exclusion between the timing tasks and the timing tasks is realized, and the problem of singleness of the timing tasks is effectively solved.
In one embodiment, the step of sending the metadata of the target timing task to a task queue of a scheduling end corresponding to the running mode includes: acquiring a second task identifier of the target timing task; performing hash operation on the second task identifier to obtain a hash value of the second task identifier; and determining a target scheduling end from scheduling ends corresponding to the running mode of the target timing task according to the hash value, and sending the metadata of the target task to a task queue of the target scheduling end.
In this embodiment, when the main control end sends the target timing task to the scheduling end corresponding to the target timing task operation mode, according to the hash value of the task identifier of the target timing task, the scheduling end corresponding to the hash value of the task identifier is determined from the multiple scheduling ends corresponding to the target timing task operation mode, and the metadata of the target timing task is sent to the task queue of the scheduling end, so that the timing task is scheduled to different scheduling ends for processing, the multi-server multi-system processing of the timing task is realized, the accumulation of the task amount of the same scheduling end is avoided, and the processing of the timing task is not affected by the performance of a single machine.
In an embodiment, before the step of reading the operation period of each timing task in the database, the main control end may obtain metadata of each timing task, where the metadata may include the operation period of the timing task, basic description information, estimated operation duration, task identifier of the dependent task, scheduling information, and operation mode. The definition mode of the operation period can adopt an expression supporting Linux Crontab; the basic description information comprises basic information such as a project to which the timing task belongs, and an API interface is provided to interface with a project management service system so as to support other service systems to inquire the basic information of the timing task; and the scheduling information records an execution server where the WEB application running the timing task is located. The centralized and unified management of the timing task information is realized by pre-storing the metadata of the timing task into the database.

The scheduling end inquires whether the metadata of the executable target timing task exists in the task queue in real time, and after the main control end sends the metadata of the target timing task to the task queue of the scheduling end, the scheduling end inquires the metadata of the target timing task and schedules an execution server where the WEB application running the target timing task is located to execute the target timing task so as to realize the function of the timing task.
According to the timed task processing method, after the main control end sends the target timed task to the task queue corresponding to the running mode according to the running mode of the target timed task, the metadata of the target timed task in the task queue is inquired, the execution server is called according to the metadata to execute the target timed task, the timed task is scheduled to different scheduling ends, the scheduling end calls the execution server to execute the target timed task, the scheduling of the timed task and the execution of the timed task are decoupled by using the task queue, the processing work of the timed task among multiple servers and multiple systems is realized, the processing of the timed task is not influenced by the performance of a single machine, the generation of performance bottleneck and the reduction of the execution accuracy and the frequency of the timed task are effectively avoided, and the expansion and contraction of the scheduling ends according to the performance requirements can be realized.
In one embodiment, the mode of operation includes a native run code type; the step of calling the execution server to execute the target timing task according to the metadata comprises the following steps: determining a first execution server from the metadata, and pulling a program code corresponding to the target timing task from the main control end; sending a program code to a first execution server, wherein the program code is used for indicating the first execution server to run the program code; and receiving result data returned by the first execution server.

The main control end can upload program codes corresponding to the timing tasks in advance so that the scheduling end can pull the program codes. The embodiment provides processing schemes for different types of timing tasks, realizes the function of the timing tasks by remotely deploying and operating program codes, effectively improves the processing efficiency of the timing tasks, and avoids the accumulation of the timing tasks.
