Based on the above hardware structure, an embodiment of the scheduling method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a task scheduling method according to a first embodiment of the present invention, where the method is used for scheduling devices, and the method includes the following steps:
step S11: and reading the target scheduling message of the first message queue.
In a specific implementation process, the first message queue refers to a message queue for storing scheduling messages consumed immediately, the terminal device obtains the scheduling messages in the first message queue in real time, and the target scheduling message is the scheduling message read in real time at any moment in the first message queue. Specifically, the target scheduling message is added to the first queue message (a specific adding time is described below) through the third message queue by the task management device, and the purpose of adding the scheduling message for task scheduling to the message queue is to decouple the sending and execution of the scheduling message, so that the subsequent scheduling device can be used at any time, and the flexible and efficient technical effect of task scheduling is achieved.
Step S12: judging the service state of the configured scheduling service instance; and the service state of the scheduling service instance is configured by receiving the service state information broadcasted by the second message queue.
It should be noted that the execution subject of the present invention is a scheduling device, the scheduling device is installed with a computer program, and when the scheduling device executes the computer program, the scheduling method of the present invention is implemented. The scheduling device also comprises a scheduling service instance, the scheduling device completes the final scheduling task through the scheduling service instance, namely, executes the selected execution script of the invention, and one scheduling device can comprise a plurality of scheduling service instances or one scheduling service instance.
The scheduling information is created and issued by the task management device (also called scheduling server), and the target scheduling information is the scheduling information issued by the task management device when the task scheduling method of the present invention is executed.
The scheduling messages issued by the task management device are all delayed, and after the task management device creates the scheduling messages, the scheduling messages are sent to a third message queue (also called a delay queue). When one scheduling message in the third message queue arrives at the corresponding delay time, the third message queue adds the scheduling message to the first message queue (also called a task queue); the scheduling messages in the first message queue will be consumed immediately by the scheduling device, i.e. the scheduling messages in the first message queue will be read immediately.
It is to be understood that the target scheduling message has a target delay time, the target scheduling message is added from the third message queue to the first message queue when the target delay time is reached, and the target scheduling message is created by the task management device and sent to the third message queue.
It should be noted that, based on the operation or requirement of the user, the task management device creates the target scheduling message and adds the target scheduling message to the third message queue, where the target scheduling message sets a delay time (the messages in the delay message queue all have delay times, and the delay times corresponding to different messages are different and can be long or short, and for immediate execution, the delay time is set to be the shortest delay time, for example, 1ms), and the delay time of the target scheduling message is the target delay time; when the target delay time is reached, the third message queue takes out the target scheduling message and puts the target scheduling message into the first message queue, and then step S11 is executed without waiting; and a certain scheduling message in the third message queue needs to wait for the delay time corresponding to the scheduling message to arrive, and then the scheduling message can be added into the first message queue for direct consumption.
It should be noted that, the number of scheduling devices generally used for task scheduling is plural, and the second message queue is a broadcast queue, that is, a message is issued in a broadcast manner. In some embodiments, the scheduling device may also include one, the second message queue being a point-to-point message queue.
The service state information comprises start service information and pause service information, the service state of the scheduling service instance is that the service is started after the scheduling device performs service state configuration of the scheduling service instance based on the start service information, and the service state of the scheduling service instance is that the service is paused after the scheduling device performs service state configuration of the scheduling service instance based on the pause service information.
Step S13: and if the service state is that the service is opened, determining a selected execution script corresponding to the target scheduling message and used for executing the scheduling task in a local memory.
It should be noted that, only when the service state is that the service is opened, the target scheduling message may be continuously consumed, that is, the step of determining the selected execution script for executing the scheduling task corresponding to the target scheduling message in the local memory is performed.
If the service state is that the service is suspended, configuring the execution time of the target scheduling message by using a preset minimum delay time so as to obtain a new target scheduling message; and adding the new target scheduling message to a third message queue so that the third message queue adds the new target scheduling message to the first message queue when the preset minimum delay time is reached.
It should be noted that the preset minimum delay time may be set by the user based on the requirement, for example, 1 ms. When the service state is that the service is suspended, the scheduling device cannot consume the target scheduling message, and needs to configure a new execution time (consumption time of the scheduling message), that is, configure a new delay time (the new delay time is the preset minimum delay time), and add the new delay time to the third message queue, so as to enable the third message queue, and when the preset minimum delay time is reached, add the new target scheduling message to the first message queue, so as to implement the step of re-consumption.
Further, if the service state is that the service is opened, the step of determining a selected execution script corresponding to the target scheduling message for executing the scheduling task in the local memory includes:
if the service state is that the service is opened, acquiring instance version information and queue version information of the scheduling service instance, wherein the queue version information is version information corresponding to the first message queue, the second message queue and the third message queue; and when the instance version information and the queue version information meet preset conditions and the task state information of the target scheduling message is that a task is started, determining the selected execution script in a local memory, wherein the task state information is broadcasted by the second message queue.
It should be noted that the service status information and the task status information are created by the task management device and sent to the second message queue. When a plurality of scheduling devices are provided, the first message queue is a broadcast queue, that is, the service state information includes service state information corresponding to the plurality of scheduling devices, the task state information includes task state information corresponding to a plurality of target scheduling messages, and the service state information and the task state information are respectively sent in a broadcast message manner.
Generally, the preset condition is that the instance version information and the queue version information are consistent. When the instance version information and the queue version information are that the instance version number is lower than the queue version number, the target scheduling message may be configured with a minimum delay time (e.g., 1ms), and the configured target scheduling message is added to the third message queue, so as to continue to make the configured target scheduling message execute the steps of the task scheduling method of the present invention. If the instance version information and the queue version information indicate that the instance version number is higher than the queue version number, discarding the target scheduling message, returning to step S11 again, and waiting for reading a new target scheduling message in the first message queue to continue executing the steps of the scheduling method of the present invention.
In addition, when the instance version information and the queue version information meet preset conditions and the configured task state is that the task is suspended, a timing task expression of the target scheduling message is obtained, and the next execution time and the current time are determined by using the timing task expression; taking the difference between the next execution time and the current time as a configuration delay time; configuring the target scheduling message by using the configuration delay time to obtain a configured target scheduling message; and adding the configured target scheduling message to the third message queue to continue executing the task scheduling step of the invention.
Specifically, the target scheduling message includes a target trigger name and a target task name; said step of determining said selected execution script in said local memory comprises: indexing a selected instance name and a selected method name in the local memory using the target trigger name and the target task name; indexing the selected execution script in the local memory using the selected instance name and the selected method name.
It should be noted that the trigger names and task names included in different scheduling messages are different, and the corresponding instance names and method names are different; different instance names and method names correspond to different execution scripts; it is understood that the instance name and method name definitions are referred to as a key from which the corresponding value (execution script) is found.
Further, before the step of indexing a selected instance name and a selected method name in the local memory using the target trigger name and the target task name, the method further comprises: receiving a preset execution script sent by the first message queue, a preset trigger name corresponding to the preset execution script and a preset method name corresponding to the preset execution script, wherein the preset execution script comprises the selected execution script, the preset trigger name comprises the selected trigger name, and the preset method name comprises the selected method name; and storing the preset execution script, the preset trigger name and the preset method name in the local memory.
It will be appreciated that the execution script is also published by the second message queue, received and stored by the scheduling device, to enable utilization of the execution script.
In other embodiments, if the corresponding execution script is not found in the local memory, the native system stored in the scheduling device may search for the corresponding selected execution script, and when the selected execution script is found, step S13 is executed. If the selected execution script is found, the scheduling is stopped.
It should be noted that, the message attributes of the scheduling messages in the first message queue and the third message queue of the present invention refer to table 1, where table 1 is as follows:
TABLE 1
Referring to table 1, the target scheduling message includes a target trigger name and a target task name, the scheduling messages in the second message queue and the third message queue both have their own triggers and their own target tasks, the triggers and the tasks are combined information, and the corresponding selected combined information (selected instance name and selected method name) needs to be determined according to the combined information.
It can be understood that the selected execution script corresponding to the target scheduling message is determined by locally storing the target trigger and the target task in the target scheduling message as a basis, that is, the corresponding relationship is that the target trigger and the target task are used as the combination information, and the script is correspondingly executed.
Further, after the step of indexing the selected execution script in the local memory using the selected instance name and the selected method name, the method further comprises: receiving version updating data broadcasted by the second message queue, wherein the version updating data is sent to the second message queue by the task management equipment; and updating the scheduling service instance by utilizing the version updating data.
That is, the version of the scheduling service instance in the scheduling device can be flexibly updated, and the version is updated based on the version update data issued by the task management device through the second message queue, so as to ensure that the version information and the queue version information of the scheduling service instance in the scheduling device meet the preset condition.
In some embodiments, the first message queue has four types, and the specific definition of the four types refers to table 2, where table 2 is as follows:
TABLE 2
For the four different types of messages in table 2, the attribute information included in them refers to table 3, table 4, table 5, and table 6, where table 1 is the attribute at least included in the VERSION message, table 4 is the attribute at least included in the SERVICE message, table 5 is the attribute at least included in the TASK message, and table 6 is the attribute at least included in the NEW _ TASK message. Tables 3, 4, 5 and 6 are as follows:

TABLE 4
| Properties | Description of the invention |
| node | And scheduling the name of the service node, and if the name is null, indicating that all the nodes need to be processed |
| option | Operation, if 1, then on, if 2, then off |

Referring to fig. 3, fig. 3 is a flowchart illustrating a task scheduling method according to a second embodiment of the present invention.
Specifically, the explanation will be made by taking fig. 3 as an example. When the scheduling device comprises a plurality of scheduling devices, each scheduling device at least comprises one scheduling service instance, the scheduling device needs to judge whether the service state of each scheduling service instance in each scheduling device is opened or not after reading the target scheduling message of the first message queue type, and when a selected scheduling service instance with the service state of being opened exists in all scheduling service instances, the scheduling device continues to determine whether the instance version information is matched with the queue version information or not; when the instance version information is matched with the queue version information, whether the task state of the target scheduling message is started or not is continuously judged; if the example version information is that the example version number is high, the target scheduling message cannot be consumed, discarding the target scheduling message, and if the queue version information is that the queue version number is high, configuring minimum delay time for the target scheduling message, and adding the minimum delay time to a third message queue; when the task state is that the task is started, whether the task state of the target scheduling message in the corresponding selected scheduling service instance is started or not is continuously judged, namely, one target scheduling message cannot be executed by all the selected scheduling service instances and is only executed by one part; when the task state of the target scheduling message is pause, determining the execution time for executing the target scheduling message next time (the execution time is usually the time after the current execution time) based on the timing task expression of the target scheduling message, configuring the target scheduling message by using the execution time, and adding the target scheduling message to a third message queue so as to continue to enable the configured target scheduling message to be consumed by other service instances to execute the steps of the scheduling method; and when the task state of the target scheduling message is closed, discarding the target scheduling message.
When the service states of the scheduling service instances are all suspended, the target scheduling message may be configured with a minimum delay time (e.g., 1ms), and the configured target scheduling message is added to the third message queue, so as to continue to be consumed by other service instances, so as to execute the steps of the scheduling method of the present invention.
When the task state of the target scheduling message in the corresponding selected scheduling service instance is on, the timed task expression type in each target scheduling message is continuously judged, when the timed task expression type is timed execution, the difference between the current execution time and the current time needs to be determined, when the current execution time of one target scheduling message is after the current time, the target scheduling message is added to a third message queue (the difference between the current execution time and the current time is used as delay time for configuring the target scheduling message), and when the current execution time of one target scheduling message is before the current time, the target scheduling message is directly consumed.
When the task state of the target scheduling message in the corresponding selected scheduling service instance is started and the type of the timing task expression is interval execution, the target scheduling message is directly consumed, the timing task expression in the target scheduling message is utilized to calculate the next execution time, the target scheduling message is configured by utilizing the next execution time, and the configured target scheduling message is added to a third message queue.
When the task state of the corresponding selected scheduling service instance is suspension, a target scheduling message may be configured with a minimum delay time (e.g., 1ms), and the configured target scheduling message is added to the third message queue, so as to continue to make the configured target scheduling message perform the steps of the scheduling method of the present invention.
The technical scheme of the invention provides a task scheduling method which is applied to scheduling equipment, wherein the scheduling equipment comprises a scheduling service instance, and the method comprises the following steps: reading a target scheduling message of a first message queue; judging the service state of the configured scheduling service instance; the service state of the scheduling service instance is configured by receiving service state information broadcasted by a second message queue; and if the service state is that the service is opened, determining a selected execution script corresponding to the target scheduling message and used for executing the scheduling task in a local memory.
In the existing scheduling method, technicians need to manually configure the service state of the scheduling service instance in the scheduling device, so that when the scheduling device is used for task scheduling, the consumed time is long, and the scheduling efficiency is low. In the invention, the scheduling equipment configures the service state of the scheduling service instance based on the service state information broadcasted by the second message queue, and does not need the user to manually configure the service state, so that the time consumption is less, and the scheduling efficiency is higher. Therefore, the task scheduling method achieves the technical effect of improving the scheduling efficiency.
The invention receives version updating data, dynamic scripts, service state information, task state information and the like in the second message queue, so that the scheduling service has the capability of expanding scheduling tasks during running, the service state and the task state can be flexibly adjusted, the remote updating of the version of the scheduling service instance and the remote updating of the execution script can be realized, and the updating process is flexible and convenient; meanwhile, the service state information and the task state information sent by the second message queue can be used for dynamically managing the scheduling instances and the scheduling tasks (scheduling messages) (service state configuration and task state configuration), and even managing the specified tasks of the specified scheduling instances, so that the task scheduling flexibility is good.
