Technical Field

Background

The service side has a large number of timing tasks, each timing task corresponds to an execution period, for example, the execution period corresponding to the timing task may be executed once in 1 hour, and the corresponding server side may execute the timing task at time points such as 8 hours, 9 hours, 10 hours, and the like.

In general, each timed task may be stored on a corresponding downstream server, such that the downstream server may execute the timed task at an execution time corresponding to the timed task. However, in the manner of storing the timing task on the downstream server, when the information of the timing task is modified, the timing task after information update needs to be redeployed on the downstream server, so that the task modification process is complicated and takes a long time.

Research shows that the timing task is stored on the downstream server, and when the information of the timing task is modified, the timing task after information updating needs to be redeployed on the downstream server, so that the task modification process is complicated and takes long time, and the timing task is directly deployed on a plurality of downstream servers, so that the resource of the downstream servers is wasted, and the utilization rate of the resource is reduced.

Therefore, in order to solve the above problems, the present disclosure provides a method and an apparatus for performing a timing task.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

For the purpose of understanding the embodiments of the present disclosure, a method for performing a timing task disclosed in the embodiments of the present disclosure will be described in detail first.

Example one

Referring to fig. 1, a flowchart of a method for executing a timed task provided in an embodiment of the present disclosure is shown, where the method is applied to a scheduling server, and the method includes steps S101 to S103, where:

and S101, periodically acquiring the stored information of each timing task from the database.

S102, based on the information of each timing task, determining a to-be-executed timing task corresponding to the period from at least one timing task.

S103, when the scheduling time corresponding to each timing task to be executed is reached, generating a task execution request corresponding to the timing task to be executed, and sending the task execution request to the resource manager of the cluster corresponding to the timing task to be executed, so that the resource manager selects a target downstream server from at least one downstream server in the cluster to execute the timing task to be executed.

In the method, a to-be-executed timing task corresponding to a period is determined from at least one timing task based on information of each timing task periodically acquired from a database; when the scheduling time corresponding to each timing task to be executed is reached, a task execution request corresponding to the timing task to be executed is generated, and the task execution request is sent to the resource manager of the cluster corresponding to the timing task to be executed, so that the resource manager selects a target downstream server from at least one downstream server in the cluster to execute the timing task to be executed, and the target downstream server is selected from the at least one downstream server to execute the timing task, so that the timing task is not required to be sent to each downstream server in the cluster, namely, the resources of other servers except the target downstream server in the cluster are not occupied, the waste of server resources is avoided, and the utilization rate of the resources is improved. Meanwhile, the information of each timing task is stored in the database, the information of the timing tasks stored in the database can be flexibly configured, compared with a mode that each timing task is deployed on a downstream server, the configuration process of the timing tasks is simple, the consumed time is short, and the configuration efficiency of the timing tasks is improved.

For S101:

the scheduling server may periodically retrieve the stored information of each timing task from the database. The period of the scheduling server for acquiring the information of the timing task can be set according to actual needs. For example, the period may be 3 seconds, 5 seconds, and the like, that is, the scheduling server may obtain the stored information of each timing task from the database every 3 seconds; alternatively, the scheduling server may retrieve the stored information for each timed task from the database every 5 seconds.

Here, the information of the timing task may include at least one of: an Identity Document (ID), a service identifier, a cluster identifier, a scheduling period, a modification flag, a task state, scheduling time, description information, feedback information, and the like.

For S102:

after the information of each timing task is acquired, the to-be-executed timing task corresponding to the period may be determined from at least one timing task based on the information of each timing task. For example, the information of the timing task may be updated (that is, the scheduling time indicated in the information of the timing task may be updated), and then the timing task to be executed corresponding to the period may be determined from at least one timing task based on the updated information of the timing task.

In an optional implementation manner, before determining, based on information of each timing task, a timing task to be executed corresponding to the period from at least one timing task, the method may further include:

step one, selecting a target timing task from at least one timing task based on the task state indicated in the information of each timing task.

And secondly, determining a target timing task with the scheduling time to be updated from at least one target timing task based on at least one of a modification mark, the current scheduling time and a task feedback message included in the information of each timing task.

And step three, determining the updated scheduling time corresponding to the target timing task based on the scheduling period corresponding to the target timing task to be updated and the current scheduling time.

For the description of the first step, the task state may include normal, stop, and delete. Therefore, the timing task with the normal task state can be selected from at least one timing task as the target timing task according to the task state corresponding to each timing task; and screening out the timing tasks of which the task states are stop and deletion in at least one timing task.

Describing the step two, the target timing task whose scheduling time is to be updated may be determined from at least one target timing task based on at least one of the modification flag, the current scheduling time, and the task feedback message included in the information of each timing task.

For example, the modification may be marked as a modified target timing task, determined as a target timing task whose scheduled time is to be updated. Wherein the timing task marked as modified can be a timing task whose information is modified after the last period. For example, the period corresponds to a time range from 10:10:11 (including a time point of 10:10: 11) to 10:10:15 (including a time point of 10:10: 15), the period duration is 5 seconds, the time range corresponding to the previous period is 10:10:06 to 10:10:10, and the timing task with the modified information of the timing task in the time period from 10:10:06 to 10:10:10 is determined as the target timing task whose scheduling time is to be updated.

And determining the timing task with the current scheduling time in the time range corresponding to the previous period as a target timing task with the scheduling time to be updated. Continuing to explain with the example, if the scheduling time corresponding to the target timing task a is 10:10:08, so that it is known that the target timing task a is located within the time range corresponding to the previous period, the scheduling time of the target timing task a is to be updated, that is, the target timing task a is the target timing task whose scheduling time is to be updated; if the scheduling time corresponding to the target timing task B is 10:10:00, so that the target timing task B is known not to be located in the time range corresponding to the previous period, the scheduling time of the target timing task B does not need to be updated, namely the target timing task B is not a target timing task of which the scheduling time is to be updated; if the scheduling time corresponding to the target timing task C is 10:10:20, it can be known that the target timing task C is also not located within the time range corresponding to the previous period, the scheduling time of the target timing task C does not need to be updated, that is, the target timing task C is not a target timing task whose scheduling time is to be updated.

And then, determining a target timing task with scheduling time to be updated based on the task feedback message and the current scheduling time, wherein the task feedback information may be second feedback information indicating that the task has been executed. In specific implementation, the current scheduling time can be located in a time range corresponding to the previous period, and the target timing task with the second feedback information is determined as the target timing task whose scheduling time is to be updated; and the current scheduling time is not located in the time range corresponding to the previous period, or the target timing task without the second feedback information is not the target timing task whose scheduling time is to be updated.

Finally, a target timed task whose scheduled time is to be updated may be determined based on the modification flag, the current scheduled time, and a second feedback message indicating that the task has been executed. In specific implementation, the modification flag may be a modified target timing task, or the target timing task whose current scheduling time is within a time range corresponding to the previous period and in which the second feedback information exists may be determined as the target timing task whose scheduling time is to be updated.

Explaining the step three, after the target timing task whose scheduling time is to be updated is determined, the scheduling time of the target timing task whose scheduling time is to be updated can be updated. In specific implementation, the updated scheduling time corresponding to the target timing task may be determined according to the scheduling period corresponding to the target timing task to be updated at each scheduling time and the current scheduling time. For example, if the scheduling period corresponding to the target timing task is 1 hour and the current scheduling time is 10:00:00, it may be determined that the updated scheduling time corresponding to the target timing task is 11:00: 00.

In an optional implementation manner, determining, from at least one timing task, a timing task to be executed corresponding to the period based on information of each timing task may include: and determining the timing task to be executed corresponding to the period from at least one timing task based on the scheduling time indicated in the information of each timing task and the time range corresponding to the period.

Here, based on the scheduling time corresponding to each timing task, a timing task whose scheduling time is within the time range corresponding to the period may be selected from at least one timing task, and the selected timing task may be determined as the to-be-executed timing task corresponding to the period. Or, based on the updated scheduling time indicated in the timing task information and the time range corresponding to the period, the to-be-executed timing task corresponding to the period may be determined from at least one timing task, and the selected timing task may be determined as the to-be-executed timing task corresponding to the period.

For example, if the time range corresponding to the period is 10:10:11 (including the time point of 10:10: 11) to 10:10:15 (including the time point of 10:10: 15), according to the scheduling time corresponding to each timing task, the timing task whose scheduling time is in the time range is determined as the to-be-executed timing task corresponding to the period. For example, if the scheduling time corresponding to the timing task a is 10:10:12, the timing task a is a to-be-executed timing task corresponding to the period; and if the scheduling time corresponding to the timing task B is 10:10:20, the timing task B is not the to-be-executed timing task corresponding to the period.

Here, when determining a to-be-executed timing task corresponding to the period from at least one timing task based on the scheduling time indicated by the information of each timing task and the time range corresponding to the period, the method may include:

firstly, based on the scheduling time corresponding to each timing task and the time range corresponding to the period, determining the historical to-be-executed timing task corresponding to the previous period, and determining the timing task of which the corresponding scheduling time is located in the period.

And secondly, determining whether the information of the historical to-be-executed timed task corresponding to the previous period comprises second feedback information indicating that the task is executed.

And thirdly, determining the historical to-be-executed timed task which does not include the second feedback information in the historical to-be-executed timed task corresponding to the previous period and the timed task corresponding to the scheduling time in the period as the to-be-executed timed task corresponding to the period.

In the embodiment of the disclosure, the time range corresponding to the previous period can be determined according to the period of the information of the timing task acquired by the scheduling server and the time range corresponding to the period; and determining the historical to-be-executed timed task with the scheduling time in the previous period based on the scheduling time corresponding to each timed task. Meanwhile, the scheduled time or the timing task whose updated scheduled time is within the time range corresponding to the period may be determined as the timing task that needs to be executed in the period, that is, the timing task whose corresponding scheduled time is within the period is determined.

Further, whether second feedback information indicating that the task has been executed is included in the information of the historical to-be-executed timed task corresponding to the previous period can be detected, and if yes, the historical to-be-executed timed task is represented to be successfully scheduled in the previous period; if not, the historical to-be-executed timing task fails to be scheduled in the last period. Therefore, the historical to-be-executed timed task that failed to be scheduled in the previous period needs to be determined as the to-be-executed timed task corresponding to the period, and is scheduled and executed again in the period. If the scheduled execution of the timed task fails in multiple consecutive periods (for example, the scheduled execution fails in 3 consecutive periods), it may be a problem to characterize the service cluster executing the timed task, so that a notification message of the scheduled failure of the timed task may be sent to the resource manager, and meanwhile, an updated scheduling time may be determined for the timed task based on the scheduling period and the scheduling time of the timed task, so as to continue to schedule the timed task at the updated scheduling time point.

Here, the historical to-be-executed timed task (i.e., the historical to-be-executed timed task that failed to be scheduled in the previous cycle) that does not include the second feedback information in the historical to-be-executed timed task corresponding to the previous cycle and the timed task whose corresponding scheduling time is within the cycle may be determined as the to-be-executed timed task corresponding to the cycle.

For S103:

in specific implementation, the to-be-executed timed tasks corresponding to the period may be sequenced, and when the scheduling time corresponding to each to-be-executed timed task is reached according to the sequence, the task execution request corresponding to the to-be-executed timed task is generated, where the to-be-executed timed task corresponding to the period may include a historical to-be-executed timed task that does not include the second feedback information in the historical to-be-executed timed task corresponding to the previous period, and a timed task whose corresponding scheduling time is within the period.

For example, the historical to-be-executed timed task may be set before the timed task in the period at the corresponding scheduling time (i.e. preferentially generating the corresponding task execution request for the historical to-be-executed timed task), and if there are multiple historical to-be-executed timed tasks, the multiple historical to-be-executed timed tasks may be randomly ordered, where a time interval between two adjacent historical to-be-executed timed tasks at which the task execution request is generated may be less than or equal to a set interval value (e.g. the set interval value may be 1 millisecond). And then, according to the scheduling time, sequencing the timing tasks whose corresponding scheduling time is in the period, for example, placing the timing task before the scheduling time in front of the timing task after the scheduling time.

For example, if the to-be-executed timing task corresponding to the period includes: a timing task A to be executed, a timing task B to be executed, a timing task C to be executed, a timing task D to be executed and a timing task E to be executed; the timing task C to be executed and the timing task D to be executed are historical timing tasks to be executed, which do not include second feedback information, in the historical timing tasks to be executed corresponding to the previous period; the timing task A to be executed, the timing task B to be executed and the timing task E to be executed are timing tasks with corresponding scheduling time in the period, the scheduling time corresponding to the timing task A to be executed is 10:10:01, the scheduling time corresponding to the timing task B to be executed is 10:10:03, and the scheduling time corresponding to the timing task E to be executed is 10:10: 02. Therefore, it can be seen that the scheduling order of each timing task to be executed may be: the method comprises the steps of a to-be-executed timing task C, a to-be-executed timing task D, a to-be-executed timing task A, a to-be-executed timing task E and a to-be-executed timing task B.

Then, according to the ranking sequence, a task execution request is generated for the timing task C to be executed, and then a task execution request is generated for the timing task D to be executed, where a time interval for generating the task execution request between the timing task C to be executed and the timing task D to be executed may be less than or equal to a set interval value (for example, the set interval value may be 1 millisecond); and further, according to the scheduling time corresponding to the to-be-executed timed task a, the to-be-executed timed task E and the to-be-executed timed task B, when the scheduling time corresponding to each to-be-executed timed task is reached, a task execution request corresponding to the to-be-executed timed task is generated.

In another embodiment, the corresponding scheduling time may also be generated for the historical to-be-executed timed task that does not include the second feedback information in the historical to-be-executed timed task corresponding to the previous period, and in specific implementation, the scheduling time corresponding to each historical to-be-executed timed task may be generated based on a time range corresponding to the period. For example, if the period corresponds to a time range of 10:10:11 to 10:10:15, the scheduling time corresponding to the historical to-be-executed timing task may be 10:10:11.05 (to the precision of milliseconds).

After the corresponding scheduling time is determined for each historical to-be-executed timing task, the timing task whose corresponding scheduling time is within the period and the historical to-be-executed timing task which does not include the second feedback information in the historical to-be-executed timing task corresponding to the previous period may be sequenced according to the scheduling time, and according to the generated sequence, after the scheduling time corresponding to each to-be-executed timing task is reached, the task execution request corresponding to the to-be-executed timing task is generated.

After generating a task execution request corresponding to a timing task to be executed, the task execution request may be sent to a resource manager of a cluster corresponding to the timing task to be executed, and the resource manager selects a target downstream server from at least one downstream server in the cluster to execute the timing task to be executed.

In the embodiment of the disclosure, the scheduling server may perform a working state at the scheduling time corresponding to each to-be-executed timing task, that is, generate a task execution request corresponding to the to-be-executed timing task at the scheduling time corresponding to each to-be-executed timing task; the scheduling server can enter a dormant state at other times except the non-scheduling time, so that the excessive use of the scheduling server is avoided, and the waste of resources is avoided.

In an alternative embodiment, the method may further comprise:

firstly, if a task execution request triggered by a user aiming at any timing task is received, a task execution request corresponding to any timing task is generated.

And secondly, sending a task execution request corresponding to any timing task to a resource manager of a cluster corresponding to any timing task, so that the resource manager selects a target server from at least one downstream server in the cluster to execute any timing task.

In the embodiment of the present disclosure, the timing task may also be triggered manually, so that the downstream server executes the triggered timing task. In specific implementation, when receiving a task execution request triggered by a user for any timing task, a scheduling server may generate a corresponding task execution request for the triggered timing task, and may send the task execution request to a resource manager of a cluster corresponding to the triggered timing task in real time, so that the resource manager selects a target server from at least one downstream server in the cluster to execute any timing task.

It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.

And S202, updating the information of the timing task based on the task feedback information, and storing the updated information of the timing task in a database.

The first feedback information is generated after the downstream server receives the task execution request corresponding to the timing task, and the second feedback information is generated after the downstream server executes the timing task.

In the embodiment of the disclosure, after receiving the task execution request sent by the scheduling server, the downstream server may send first feedback information indicating that the task execution request has been received to the management server. And the downstream server may transmit second feedback information indicating that the task has been executed to the management server when executing the corresponding timed task in response to the received task execution request. The management server can receive task feedback information sent by a downstream server for the timed task, wherein the task feedback information comprises first feedback information indicating that a task execution request is received or second feedback information indicating that the task is executed.

And step four, when detecting that the task identifier exists in the task list, storing the information of the timing task to be registered in a database, and setting the task state indicated in the information of the timing task as normal.

Here, the user can register the timing task through the management server. In specific implementation, a user can trigger a task registration request and send information of a timing task to be registered to a management server. And the management server determines a task identifier and a service identifier corresponding to the task registration request from the information of the timing task to be registered. Further, a task list corresponding to the downstream server may be obtained from the downstream server corresponding to the service identifier, where the task list may include task identifiers of timing tasks corresponding to the downstream server. Then, whether a task identifier corresponding to a request to be registered exists in the received task list can be judged, if yes, information of the timed task to be registered is stored in a database, and a task state indicated in the information of the timed task is set to be normal; if the timing task to be registered does not exist, the timing task to be registered is not allowed to be registered, namely, the information of the timing task to be registered is not stored.

In an alternative embodiment, the method may further comprise: and responding to a task modification request triggered by a user, and modifying the information to be modified of the timing task corresponding to the task modification request.

Here, the information of any one of the timing tasks stored in the database may be modified by the management server. In specific implementation, the management server may respond to a task modification request triggered by a user, and modify information to be modified of a timing task corresponding to the task modification request. For example, information such as the scheduling time, the scheduling period, and the task status of the timed task a may be modified. And if the task state of the timing task is modified to be deleted, the timing task is characterized to be deleted.

In an alternative embodiment, the method may further comprise: and responding to a task query request triggered by a user, and querying information of at least one timing task corresponding to the task query request.

Here, the information of any one of the timed tasks stored in the database may be queried by the management server. In specific implementation, the management server may respond to a task query request triggered by a user to query information of the corresponding at least one timing task.

For example, when querying the timing task, the timing task to be queried may be determined based on at least one of the task status, the scheduling period, the task identifier, the service identifier, and the like of the timing task. Further, the information of the determined timed task to be queried may be queried.

The method for executing the timing task provided by the embodiment of the disclosure has the same technical characteristics as the method for executing the timing task provided by the first embodiment, so that the same technical problems can be solved, and the same technical effects can be achieved.

Based on the same inventive concept, the embodiment of the present disclosure further provides a device for executing a timing task corresponding to the method for executing a timing task, and since the principle of solving the problem of the device in the embodiment of the present disclosure is similar to that of the method for executing a timing task in the embodiment of the present disclosure, the implementation of the device may refer to the implementation of the method, and repeated details are omitted.
