Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The first embodiment is as follows:
the embodiment of the present invention provides a method for scheduling and controlling a timed task of a cluster system, where the timed task may be a task triggered to be executed at a preset time or a task triggered to be executed according to a preset period, where triggering of the timed task refers to starting execution of the timed task when an execution condition of the timed task is met, for example, when a preset trigger time of the timed task is reached, the timed task starts execution.
Timing tasks are a very common type of function in existing systems, such as management systems. For example, the timing task may be to compress newly acquired data in the database periodically, to screen the data once at a fixed time every day, to perform database backup at a time point of zero time every day, to perform report statistics, and so on. After the timing task is created, the server or application creating the timing task may automatically start a thread or process to make the timing task execute at a specified trigger time or according to a certain period.
Fig. 1 is a flowchart of an implementation of a method for scheduling and controlling a cluster system timing task according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
s1: and acquiring the node number of the cluster node.
In this embodiment, each node in the cluster is numbered to obtain a node number of each cluster node, which is used to distinguish different cluster nodes, for example, a unique identity is generated for each cluster node in a random generation manner.
S2: the cluster node accesses the distributed cache service to apply for the certificate, further, the certificate is unique and is cache data containing node identification and certificate failure time, wherein the node identification is a node number of the cluster node which successfully applies for the certificate.
In the cluster environment of this embodiment, each cluster node applies for a credential for the distributed cache service, and the cache server maintains a node number list, and simultaneously, each cluster node subscribes to a timed task message to the distributed cache service by using the message publishing and subscribing functions of the distributed cache service.
S3: and the cluster node applying for the certificate is used as a scheduling node to obtain the scheduling control authority.
In this embodiment, the cluster node that obtains the credential is used as a scheduling node for scheduling and selecting a certain cluster node to execute the timing task. The effect of using the unique credentials is to ensure that only one scheduling node in the current cluster environment is scheduling.
S4: and the scheduling node dynamically calculates the node number of the execution node from the cluster node according to the node routing rule, and the execution node obtains the execution authority to execute the timing task.
In this embodiment, the node routing rule includes: sequential selection, reverse order selection, round robin selection, random selection, assigned numbers. Specifically, the method comprises the following steps: 1) and (3) sequential selection: for example, the selection is started from the first node to the last node according to the node number sequence; 2) selecting a reverse narrative: for example, the selection is started from the last node to the first node according to the node number sequence; 3) and (3) polling selection: sending out inquiry information at regular time, inquiring whether the nodes in each cluster system can provide services according to a certain sequence, and inquiring the next and repeated process after the services are finished; 4) random selection: selecting a node, for example, based on a random number; 5) designation number: for example, specifying the execution node according to actual needs.
It can be understood that the node routing rules in this embodiment may be used in a cross manner, for example, when the executing node is selected for the first time, the executing node is selected in a sequential selection manner, after the timing task is executed, the executing node in the next time selects the executing node in a random selection manner, and the like, and the selection of the routing rules of different nodes may be performed according to actual requirements, so as to ensure flexibility of executing node selection, which is not specifically limited herein.
S5: the scheduling node issues a timing task message to the distributed cache, the timing task message comprises a node number of an execution node, and the cluster node subscribes to receive the timing task message and judges whether the execution node has an execution authority.
Specifically, the cluster node receives the subscribed timed task message, and simultaneously judges whether the executing node of the timed task is itself, if so, the cluster node has an executing authority to execute the timed task, otherwise, the cluster node ignores the timed task.
It can be understood that, in this embodiment, after the scheduling node obtains the node number of the executing node through calculation, it may also only return the node number, and when the cluster system issues the timing task, the cluster system issues the node number (i.e., the timing task executor) and the timing task to the cluster node subscribing the timing task at the same time.
The implementation mode of the embodiment is simple, no additional development system is needed, so that the cluster system is low in complexity and low in development cost, meanwhile, since development and code maintenance are not needed on a plurality of systems, the development efficiency is high, and since external interface packaging is not needed on a timing task execution program, the system safety is improved.
Further, the scheduling node can renew the certificate failure time in a renewal mode before the certificate failure time is reached, namely, the certificate failure time is revised again in a renewal mode before the certificate failure, once a certain cluster node successfully applies for the certificate, the cluster node can always hold the certificate through the renewal mode and always has scheduling authority to perform node scheduling, the effect is equal to that of single-machine scheduling, and other cluster nodes do not apply for the certificate, so that the scheduling authority does not exist, a plurality of nodes with the scheduling authority under a cluster system are avoided, and the scheduling efficiency is improved.
Further, when the scheduling node goes down, the voucher of the scheduling node is not renewed before the voucher expiry time, so that after the voucher expires, the rest cluster nodes apply for the voucher again to the distributed cache and renew for a new scheduling node to execute the scheduling task as required.
The above process is for improving the fault tolerance of the cluster system, and because the credentials held by the cluster nodes in this embodiment include the credential failure time, when the scheduling node goes down due to a fault, the credentials are temporarily failed in the credential failure time, so that other nodes in the cluster system can apply for the credentials and have a scheduling authority, it is ensured that the timing task is not delayed due to the down of the scheduling node, it is ensured that the timing task continues to be executed, and the reliability of the cluster system is improved.
As shown in fig. 2, a specific flowchart of the method for controlling scheduling of a cluster system timing task provided in this embodiment is shown. As can be seen from fig. 2, the method is divided into two parts: the logic controls the timing task part and the timing task part, and the flow is described below with cluster node a and cluster node B.
Node a performs the process described below, assuming that node a applies for the first application to the credential when applying for it.
S11: node a generates a node number, which is a unique identification of node a, e.g., "a".
S12: the node A starts the voucher application and simultaneously starts a renewal timer, and when the node A applies for the voucher, the renewal timer checks the current time so as to realize voucher renewal before the voucher failure time.
S13: the node A applies for obtaining a certificate from the distributed cache, wherein the certificate comprises: node identification and certificate expiration time, optionally, the data structure of the certificate includes: a KEY, a value and a certificate expiration time, wherein the KEY is a fixed value for performing the certificate identification, such as "SCHEDULE _ KEY", the value is used for saving the node identification, i.e., the node number "a" of the node a, and the certificate expiration time can be set according to the requirement, such as 60 s.
S14: and judging whether the voucher is applied by other nodes, namely judging whether the voucher with the KEY of 'SCHEDULE _ KEY' exists, if so, entering the next step, otherwise, returning the voucher to be null.
S15: a credential for the distributed cached data is generated while node a owns the credential.
S16: after the node A as a scheduling node applies for the certificate, the 'holding certificate mark' is updated to be 'yes'.
S21: the node A starts a task timer, the timer is used for checking whether the current time point meets the preset time condition of the timing task, and if yes, the next step is carried out.
S22: and judging whether the node A holds the certificate, namely judging whether the 'holding certificate mark' of the node A is 'yes', and if the result is 'yes', entering the next step.
S31: node a obtains a list of cluster node IDs from the distributed cache service.
S32: the node number of the executing node is calculated according to the node routing rule, for example: "B".
S33: the node A issues a timed task message to the distributed cache service, and the execution of the timed task is artificially 'B', namely the node B has the execution authority as an execution node.
S41: node a subscribes to the distributed cache service for timed task messages.
S42: node a receives the timed task message from the distributed caching service and ignores the timed task message because the executor of the message is a "B".
The node B performs the procedure as follows.
S11: the node B generates a node number, which is a unique identification of the node B, e.g., "B".
S12: the node B starts the voucher application and simultaneously starts a renewal timer, and when the node B applies for the voucher, the renewal timer checks the current time so as to realize voucher renewal before the voucher failure time.
S13: the node B applies for the acquisition credential from the distributed cache.
S14: node B checks that the credential has been applied by node A, i.e., the credential with the KEY "SCHEDULE _ KEY" exists and has the value "A".
S16: node B updates the "holding credential flag" to "no".
S21: the node B starts a task timer, the timer is used for checking whether the current time point meets the preset time condition of the timing task, and if yes, the next step is carried out.
S22: judging that the 'holding certificate mark' of the node B is known to be 'no', and then the node B does not execute the task.
S41: the node B subscribes to the distributed cache service for the timed task message.
S42: the node B receives the timing task message from the distributed cache service, and as the executor of the timing task message is 'B', the node B serves as an execution node, obtains the execution authority and executes the timing task.
When the node a goes down, the node B may apply for the voucher and continue the voucher as needed after the voucher of the node a expires due to the voucher of the node a not continuing before the voucher expiration time, and the operation process of the node B is the same as that of the node a.
It can be understood that, when the scheduling node performs scheduling, all cluster nodes are selected according to the node routing rule, so that a situation that the scheduling node itself serves as an execution node is also allowed to occur, in combination with fig. 2, that is, the node a serves as the scheduling node, and the execution node obtained through calculation of the node routing rule may also be "a", when the node a receives the timing task message from the distributed cache service, it is known that an executor of the timing task message is "a", and at this time, the node a serves as the execution node, obtains an execution authority, and executes the timing task.
Similarly, it can be understood that, in this embodiment, after a timing task is executed once, a scheduling node of a next timing task is selected again by applying for a certificate, as long as it can be ensured that only one scheduling node of a timing task has a scheduling authority, a timing task is executed by an executing node obtained by dynamic calculation according to a node routing rule, and as for each time, the same node is not used as a scheduling node, this embodiment is not limited.
By adopting the message publishing and subscribing functions of the distributed cache service, each cluster node can receive the timing task message and is processed by the designated timing task execution node, the problem that the timing task is repeatedly executed by a plurality of cluster nodes is effectively solved, and meanwhile, the scheduling is carried out through the node routing rule, so that the load of the cluster system is balanced.
Further, in this embodiment, the cluster system is a Redis cluster system, the Redis cluster system is a high-availability and high-load cluster scheme, and the method for scheduling the timed task of the cluster system according to this embodiment can improve the execution efficiency of the timed task of the system.
The embodiment overcomes the problems of inflexible selection of execution nodes and unbalanced load of the timing task in the prior art, a new system does not need to be additionally developed in a cluster system environment, the intrusiveness of the system is small, the scheduling control authority is judged through a certificate on the premise of ensuring the safety and reliability of the cluster system, the timing task is executed through the selection of the execution nodes by the scheduling nodes, the timing task is prevented from being executed on fixed cluster nodes all the time, the load of the cluster system is balanced, and the scheduling difficulty of the timing task is reduced.
Example two:
