Description

Technical Field

[0001] This application relates to the technical field of distributed task scheduling, and particularly to a task scheduling method, apparatus, device and medium. Background Art

[0002] In the online scenario of a distributed system, there are at least two online application instances with the same function. Sometimes, tasks need to be executed regularly in the online scenario. At this time, each online application instance will execute this task. However, due to the repeated execution of the same task, the execution result of this task may be incorrect, resulting in the failure of task execution. Therefore, in the prior art, a scheduling center server is added to the distributed system, so that when executing a task, only one online application instance is selected to execute this task, avoiding the repeated execution of the task.

[0003] However, adding a scheduling center server to the distributed system is equivalent to expanding the overall architecture of the distributed system. And in order for each electronic device deployed with an online application instance to communicate with this scheduling center server, interfaces will be added, resulting in an increase in the complexity and uncertainty of the distributed system. At the same time, it also increases the probability of errors occurring during the operation of this distributed system, affecting the user experience. Summary of the Invention

[0042] In order to make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0043] In the present application, if a task to be executed is recognized, the target electronic device sends a request for obtaining an instance registration list to the registration center server, where the function of the online application instance deployed in the target electronic device is carried in the request, receives the instance registration list including each online application instance corresponding to the function of the online application instance sent by the registration center server, determines the priority of each online application instance in the instance registration list according to the IP address of each online application instance carried in the instance registration list, and determines whether the target electronic device executes the task to be executed according to the priority of each online application instance.

[0044] In order to avoid adding a scheduling center server in a distributed system and reduce the complexity and uncertainty of the distributed system, the present application provides a task scheduling method, device, equipment, and medium.

[0045] Embodiment 1:

[0046] Figure 1 A schematic diagram of a task scheduling process provided for some embodiments of the present application, the process including:

[0047] S101: If a task to be executed is recognized, the target electronic device sends a request for obtaining an instance registration list to the registration center server, where the function of the online application instance deployed in the target electronic device is carried in the request.

[0048] A task scheduling method provided by the present application is applied to an electronic device, which is located in a distributed system and is deployed with an online application instance.

[0049] In this application, a distributed system can perform at least two functions, where each function corresponds to at least two online application instances, and each online application instance is deployed on a different electronic device. In this application, the distributed system also includes a registration center server, which stores the IP addresses, identification information, and functions of all the running online application instances in the distributed system. For each online application instance accessing the distributed system, the electronic device where the online application instance is located sends the identification information, IP address, and function of the online application instance to the registration center server. After receiving the identification information, IP address, and function sent by the electronic device, the registration center server stores them in a corresponding manner. Among them, in this application, the IP address of the online application instance is the IP address of the electronic device where the online application instance is located.

[0050] And the registration center server sends broadcast information to the electronic devices corresponding to the stored online application instances at regular intervals, and receives the response information sent by the electronic devices where each online application instance is located. For the online application instances that do not send response information, it is considered that the online application instances are offline, and the information corresponding to the offline online application instances stored is deleted. That is, in this application, the online application instances stored in the registration center server are all in a working state.

[0051] In this application, the same tasks and the execution time corresponding to each task are pre-configured for the online application instances with the same function. In addition, in the distributed system, for a task, only one online application instance needs to complete the task. Therefore, when the target electronic device with an online application instance deployed recognizes that there is a task to be executed, it is necessary to determine whether the target electronic device executes the task to be executed.

[0052] To determine whether the target electronic device executes the task to be executed, in this application, if the target electronic device recognizes that there is a task to be executed, it sends a request to obtain the instance registration list to the registration center server, and the request carries the function of the online application instances deployed in the target electronic device. Specifically, in this application, when the target electronic device recognizes that there is a task to be executed with the execution time being the current time among the pre-stored tasks, it sends a request to obtain the instance registration list to the registration center server in the distributed system where the target electronic device is located.

[0053] S102: Receive the instance registration list of each online application instance corresponding to the function of the online application instance sent by the registration center server.

[0054] In this application, after the target electronic device sends a request to obtain an instance registration list to the registration center server in the distributed system where it is located, since the request carries the functions of the online application instances deployed in the target electronic device, based on this, the registration center server will identify each online application instance corresponding to the function according to the function, and send an instance registration list containing the identified online application instances to the target electronic device, where the instance registration list includes the online application instances deployed in the target electronic device.

[0055] S103: Determine the priority of each online application instance in the instance registration list according to the IP address carried by each online application instance in the instance registration list.

[0056] In this application, after the target electronic device receives the instance registration list sent by the registration center server, in order to determine whether the target electronic device executes the to-be-executed task, it can determine the priority of the online application instances deployed in the target electronic device, and then determine whether the target electronic device executes the to-be-executed task according to the priority.

[0057] Among them, in this application, the priority of each online application instance in the received instance registration list can be determined, and then the priority of the online application instances deployed in the target electronic device can be determined. Specifically, the instance registration list carries the IP address corresponding to each online application instance, and the target electronic device also pre-saves a method for determining the priority of the online application instance according to the IP address. Based on this, the target electronic device can determine the priority of each online application instance in the instance registration list according to the IP address carried by each online application instance in the instance registration list.

[0058] S104: Determine whether the target electronic device executes the to-be-executed task according to the priority of each online application instance.

[0059] In this application, after determining the priority of each online application instance in the instance registration list, it can be determined whether the target electronic device executes the to-be-executed task based on the priority of each online application instance.

[0060] Specifically, the priority corresponding to the online application instance that executes the to-be-executed task can be pre-saved in each electronic device, where the priorities saved in each electronic device are the same. Generally, the priority corresponding to the online application instance that executes the to-be-executed task pre-saved in each electronic device is the highest priority.

[0061] After the target electronic device determines the priority of each online application instance in the instance registration list, it determines the priority corresponding to the online application instance deployed in the target electronic device, and determines whether the priority is the priority corresponding to the online application instance for executing the to-be-executed task pre-saved. If so, it determines that the target electronic device executes the to-be-executed task; if not, it determines that the target electronic device does not execute the to-be-executed task.

[0062] In this application, the target electronic device deployed with online application instances obtains the instance registration list of each online application instance corresponding to the function of the online application instance from the registration center server, and then determines the priority of each online application instance according to the IP address of each online application instance carried in the registration list, and determines whether the target electronic device executes the to-be-executed task according to the priority, realizing that when performing task scheduling, there is no need to add a scheduling center server in the distributed system, reducing the complexity and uncertainty of the distributed system.

[0063] Embodiment 2:

[0064] In order to determine the priority of each online application instance in the instance registration list, on the basis of the above embodiment, in this application, determining the priority of each online application instance in the instance registration list according to the IP address of each online application instance carried in the instance registration list includes:

[0065] Sort the numerical values of the IP addresses according to the IP address corresponding to the online application instance in the instance registration list;

[0066] Determine the priority of each online application instance according to the sorting position of each online application instance in the sorting result.

[0067] In order to determine the priority of each online application instance in the instance registration list, in this application, the IP address corresponding to each online application instance carried in the instance registration list can be determined, and the IP address can be sorted according to the numerical value. Specifically, it can be sorted from largest to smallest according to the numerical value of the IP address, or it can be sorted from smallest to largest according to the numerical value of the IP address. The specific sorting rule can be pre-saved in the target electronic device and will not be limited here.

[0068] After determining the sorting result corresponding to the numerical size of the IP address, based on the sorting result, determine the sorting position of each online application instance in the sorting result, and determine the priority of each online application instance according to the sorting position.

[0069] Specifically, in the present application, when determining the priority of each online application instance according to the sorting position corresponding to the sorting result of each online application instance in the IP address, the higher the sorting position, the higher the priority of the online application instance, where the highest priority is level 0.

[0070] Figure 2 FIG. 4 is a schematic flowchart of a task scheduling method provided in some embodiments of the present application, and the process includes:

[0071] S201: If a task to be executed is recognized, the target electronic device sends a request for obtaining an instance registration list to the registration center server.

[0072] S202: Receive the instance registration list of each online application instance corresponding to the function of the online application instance sent by the registration center server.

[0073] S203: Determine the priority of each online application instance in the instance registration list according to the IP address of each online application instance carried in the instance registration list.

[0074] S204: Determine whether the priority of the online application instance deployed in the target electronic device is the highest priority.

[0075] S205: If the priority of the online application instance deployed in the target electronic device is the highest priority, determine that the target electronic device executes the task to be executed.

[0076] Embodiment 3:

[0077] In order to determine whether the target electronic device executes the task to be executed, on the basis of the above embodiments, in the present application, determining whether the target electronic device executes the task to be executed according to the priority of each online application instance includes:

[0078] If the number of tasks to be executed does not exceed a preset number threshold, determine whether the priority of the target electronic device is the highest priority;

[0079] If so, determine that the target electronic device executes the task to be executed.

[0080] Since in the present application, only the priority of one online application instance for executing the task to be executed is saved in the target electronic device, generally, the priority corresponding to the online application instance for executing the task to be executed is the highest priority. However, when the number of tasks to be executed at the same time is too large, if all the tasks to be executed are executed by the electronic device where the online application instance corresponding to the highest priority is located, it will cause an excessive load on the electronic device and increase the time consumed for executing the task to be executed.

[0081] Therefore, in order to prevent an excessive number of tasks to be executed at the same time from being executed by the electronic device where the online application instance with the highest priority is located, in this application, a quantity threshold is preset. Only when the quantity of tasks to be executed at the current moment does not exceed this quantity threshold, will the electronic device where the online application instance corresponding to the highest priority be used to execute the task to be executed.

[0082] Specifically, in this application, after determining the priority corresponding to each online application instance in the instance registration list, determine the quantity of tasks to be executed at the current moment. If this quantity does not exceed the preset quantity threshold, then determine whether the priority of the online application instance deployed in the target electronic device is the highest priority. If so, determine that the target electronic device executes the task to be executed.

[0083] In order to determine whether the target electronic device executes the task to be executed, based on the above embodiments, in this application, the method further includes:

[0084] If the priority of the target electronic device is not the highest priority, then determine that the target electronic device does not execute the task to be executed.

[0085] In this application, if after determining the priority corresponding to each online application instance in the instance registration list, it is determined that the quantity of tasks to be executed at the current moment does not exceed the preset quantity threshold, but the priority of the online application instance deployed in the target electronic device is not the highest priority, then determine that the target electronic device does not execute the task to be executed.

[0086] Embodiment 4:

[0087] In order to determine whether the target electronic device executes the task to be executed, based on the above embodiments, in this application, determining whether the target electronic device executes the task to be executed according to the priority of each online application instance includes:

[0088] If the quantity of tasks to be executed exceeds the quantity threshold, then for each task to be executed, calculate the hash value of the name of the task to be executed; calculate the modulus value of the hash value and the quantity of online application instances in the instance registration list, and determine whether the modulus value corresponds to the priority order corresponding to the priority of the target electronic device. If so, determine that the target electronic device executes the task to be executed.

[0089] To avoid having too many tasks to be executed at the same time being executed by the electronic device with the highest priority and reduce the load pressure on the electronic device corresponding to the highest priority, in this application, if the number of tasks to be executed at the current moment exceeds a preset number threshold, the hash value of the name of each task to be executed is calculated, and the modulus value of the hash value of the name of each task to be executed and the number of online application instances in the instance registration list is calculated. For each hash value, if the modulus value of the hash value and the number of online application instances in the instance registration list corresponds to the priority order corresponding to the priority of the target electronic device, it is determined that the target electronic device executes the task to be executed corresponding to the hash value.

[0090] Specifically, in this application, if the number of current tasks to be executed exceeds the preset number threshold, the hash value of the name of each task to be executed is calculated, and the modulus value of each hash value and the number of online application instances in the instance registration list is calculated. That is, for each hash value, divide the hash value by the number of online application instances in the instance registration list, and determine the remainder as the modulus value of the hash value and the number of online application instances in the instance registration list. If the modulus value corresponds to the priority order corresponding to the priority of the target electronic device, it is determined that the target electronic device executes the task to be executed corresponding to the hash value.

[0091] To determine whether the target electronic device executes the task to be executed, based on the above embodiments, in this application, the method further includes:

[0092] If the modulus value does not correspond to the priority order corresponding to the priority of the target electronic device, it is determined that the target electronic device does not execute the task to be executed.

[0093] In this application, if the number of tasks to be executed at the current moment exceeds the preset number threshold, the hash value of the name of each task to be executed is calculated, and the modulus value of each hash value and the number of online application instances in the instance registration list is calculated. That is, for each hash value, divide the hash value by the number of online application instances in the instance registration list, and determine the remainder as the modulus value of the hash value and the number of online application instances in the instance registration list. If the modulus value does not correspond to the priority order corresponding to the priority of the target electronic device, it is determined that the target electronic device does not execute the task to be executed corresponding to the hash value.

[0094] Figure 3a It is a schematic diagram of the process for the registration center server provided in some embodiments of this application to save the IP address, identification information, and functions of online application instances. As shown in this Figure 3aAs described above, the distributed system includes three online application instances, namely, online application instance one, online application instance two, and online application instance three. After online application instance one accesses the distributed system where the registration center server is located, the electronic device where online application instance one is located sends the IP address, identification information, and functions corresponding to online application instance one to the registration center server; after online application instance two accesses the distributed system where the registration center server is located, the electronic device where online application instance two is located sends the IP address, identification information, and functions corresponding to online application instance two to the registration center server; after online application instance three accesses the distributed system where the registration center server is located, the electronic device where online application instance three is located sends the IP address, identification information, and functions corresponding to online application instance three to the registration center server.

[0095] Figure 3b It is a schematic diagram of the process in which the registration center server in some embodiments of the present application sends broadcast information to the saved online application instances. As shown in Figure 3b this figure, after the registration center server sends broadcast information to the electronic devices corresponding to the saved online application instances, it receives the response information sent by online application instance two and online application instance three, and does not receive the response information sent by online application instance one. Then it is considered that online application instance one is offline, and the information corresponding to online application instance one saved is deleted.
