Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a first flowchart of a cluster topology updating method according to an embodiment of the present application.
The cluster topology updating method provided by the embodiment of the application is applied to a preset cluster node in a cluster, and can include the following steps:
step S101: receiving cluster link abnormal information sent by a target cluster node in a cluster, wherein the cluster link abnormal information comprises identification information of the target cluster node and identification information of an opposite-end cluster node connected with the target cluster node through the target cluster link; the target cluster link is a cluster link which is connected with the target cluster node and has an abnormality.
In practical application, the preset cluster node may receive cluster link abnormality information sent by a target cluster node in a cluster, and the cluster link abnormality information includes identification information of the target cluster node and identification information of an opposite-end cluster node connected to the target cluster node through the target cluster link, so that the cluster link abnormality information may reflect relevant information of the target cluster link, for example, if the target cluster node is the cluster node 2, the opposite-end cluster node is the cluster node 4, and the target cluster link is a cluster link connected between the cluster node 2 and the cluster node 4.
It should be noted that the preset cluster node may be a master node in the cluster or a node in the cluster dedicated to updating the cluster topology, and the like, and this application is not limited in this application.
Step S102: and determining cluster nodes to be deleted based on the cluster link abnormal information.
In practical application, because the cluster link exception information carries the identification information of the target cluster node and the identification information of the opposite-end cluster node, and the target cluster node and the opposite-end cluster node are connected to both sides of the target cluster link, the preset cluster node can make the target cluster link disappear in the cluster by only deleting the target cluster node or the opposite-end cluster node, so that after receiving the cluster link exception information sent by the target cluster node in the cluster, the preset cluster node can determine the cluster node to be deleted based on the cluster link exception information, so as to update the cluster topology of the cluster.
Step S103: and deleting the cluster node to be deleted and the cluster link corresponding to the cluster node to be deleted in the cluster topology of the cluster to obtain the updated cluster topology.
In practical application, after the preset cluster node determines the cluster node to be deleted based on the cluster link abnormal information, the cluster node to be deleted and the cluster link corresponding to the cluster node to be deleted can be deleted in the cluster topology of the cluster, so that the updated cluster topology is obtained.
For convenience of understanding, it is assumed that the cluster includes a cluster node 1, a cluster node 2, a cluster node 3, and a cluster node 4, when an abnormal cluster link does not occur in the cluster, the cluster topology is as shown in fig. 2, when the cluster link between the cluster node 2 and the cluster node 4 in the cluster is abnormal, it is assumed that the preset cluster node takes the node 2 as a cluster node to be deleted, the updated cluster topology is as shown in fig. 3, and if the preset cluster node takes the node 4 as a cluster node to be deleted, the updated cluster topology is as shown in fig. 4.
The application provides a cluster topology updating method, which is applied to a preset cluster node in a cluster and used for receiving cluster link abnormal information sent by a target cluster node in the cluster; determining cluster nodes to be deleted based on the cluster link abnormal information; deleting cluster nodes to be deleted and cluster links corresponding to the cluster nodes to be deleted in the cluster topology of the cluster to obtain an updated cluster topology; the cluster link abnormal information comprises identification information of a target cluster node and identification information of an opposite-end cluster node connected with the target cluster node through a target cluster link; the target cluster link is a cluster link which is connected with the target cluster node and has an abnormality. In the application, when a target cluster node is abnormal in a target cluster link connected with the target cluster node, cluster link abnormal information is actively generated and sent to the preset cluster node, so that the preset cluster node can update cluster topology based on the cluster link abnormal information.
In the cluster topology updating method provided by the embodiment of the application, the preset cluster node can determine a target cluster link based on the cluster link abnormal information in the process of determining the cluster node to be deleted based on the cluster link abnormal information; determining a target cluster link connected with the same cluster node as a first type of cluster link; determining a target cluster link which is not connected with the same cluster node as a second cluster link; determining the same cluster nodes connected by the first type of cluster links as cluster nodes to be deleted; and determining cluster nodes to be deleted in the target cluster nodes corresponding to the second cluster links.
In practical application, the abnormal condition of cluster links connected with a certain cluster node may occur due to the abnormal condition of the cluster node, at this time, each cluster link abnormality information includes identification information of the abnormal cluster node, and still taking the cluster shown in fig. 2 as an example, assuming that the cluster node 4 is abnormal, the cluster node 1, the cluster node 2 and the cluster node 3 will generate one cluster link abnormal information, that is, there will be three cluster link abnormal information, and the three cluster link abnormal information all include the identification information of the cluster node 4, at this time, if the target cluster link connected with the same cluster node is determined as a first-class cluster link and the same cluster node connected with the first-class cluster link is determined as a cluster node to be deleted, the cluster node 4 is directly used as the cluster node to be deleted and is consistent with the real abnormal reason of the cluster link; for those situations where cluster link abnormality information of the same cluster node does not exist, for example, cluster links in the cluster nodes 2 and 4 are abnormal, only the cluster node 2 or the cluster node 4 needs to be deleted at this time, so that a target cluster link which is not connected with the same cluster node can be determined as a second-class cluster link, and a cluster node to be deleted is determined in a target cluster node corresponding to the second-class cluster link.
In practical application, in the process that the cluster node to be deleted is determined in the target cluster nodes corresponding to the second type of cluster link by the preset cluster node, the cluster node with the least number of processing events can be determined as the cluster node to be deleted in the target cluster nodes corresponding to the second type of cluster link. Since the cluster nodes process a large number of events, which means that the performance of the cluster nodes is good and the amount of data of useful information stored in the cluster nodes is large, in order to reduce the influence of the cluster nodes to be deleted on the cluster performance as much as possible, the cluster node with the least number of processing events may be determined as the cluster node to be deleted from the target cluster nodes corresponding to the second type of cluster links.
In practical application, the preset cluster node may further receive node state information sent by the target cluster node before determining the real-time number of the target cluster links based on the cluster link abnormal information, where the node state information includes the number of events processed by the target cluster node. That is, the target cluster node may actively send node state information representing the number of events processed by the target cluster node to the preset cluster node, so that the preset cluster node may quickly determine the number of events processed by the target cluster node based on the node state information.
In practical application, if the same cluster node connected by the first type of cluster link is a preset cluster node, it may be that the preset cluster node is abnormal, or other nodes except the preset cluster node are abnormal, at this time, if the preset cluster node is deleted, the cluster topology updating method provided by the present application cannot be executed, so to ensure that the cluster topology can be updated normally, in the process of determining the same cluster node connected by the first type of cluster link as a cluster node to be deleted, it may be determined whether the same cluster node is the preset cluster node, and if not, the step of determining the same cluster node connected by the first type of cluster link as the cluster node to be deleted is executed.
It should be noted that, in the case that the same cluster node is a preset cluster node, the preset cluster node may be reselected from the cluster, and then the step of determining the same cluster node connected by the first type of cluster link as the cluster node to be deleted is performed.

Step S202: and combining the identification information of the cluster nodes and the identification information of the opposite-end cluster nodes connected by the target cluster nodes through the target cluster links into cluster link abnormal information.
Step S203: and sending the cluster link abnormal information to a preset cluster node so that the preset cluster node determines the cluster node to be deleted based on the cluster link abnormal information, and deleting the cluster node to be deleted and the cluster link corresponding to the cluster node to be deleted in the cluster topology of the cluster to obtain the updated cluster topology.
