[0002] Data synchronization of a Zookeeper (zk for short) cluster is a scenario that is often encountered by operation and development personnel in their work.

[0003] Currently, if data of a source zk cluster is to be synchronized to a target cluster, the data file of the registered node of the source zk cluster needs to be copied down first, and then the data file is manually copied to a specified directory of the target cluster, and the data can be synchronized only by restarting the target zk cluster. If the target cluster wants to synchronize data of another cluster in the future, the above operations need to be repeated, and the data can be synchronized only by restarting the zk cluster during the synchronization process. The operation is complicated, and the data cannot be synchronized to multiple clusters at the same time. During the restart period, services dependent on the cluster cannot be normally used.

[0028] This embodiment provides a data synchronization method applied to a computer terminal. Figure 2 This is a flowchart of a data synchronization method according to an embodiment of this application, which includes the following steps:

[0029] Step S202: Upon receiving an instruction to synchronize data from the source cluster to the destination cluster, the data synchronization process traverses the data to be synchronized in the source cluster to obtain the node data of multiple nodes in the tree structure corresponding to the data to be synchronized and the hierarchical relationship of the multiple nodes, wherein the multiple node data are stored on the multiple nodes respectively.

[0030] It should be noted that the data to be synchronized is of tree structure type, and the node data corresponding to the data to be synchronized is stored on the data nodes of the tree structure.

[0031] Step S204: Establish a first connection between the data synchronization process and the target cluster based on the Internet Protocol address of the target cluster;

[0032] Step S206: Based on the first connection relationship, send the node data and the hierarchical relationship to the destination cluster to instruct the destination cluster to create a node according to the hierarchical relationship and store the node data in the node created by the destination cluster.

[0033] By the above steps, in the case that an instruction indicating that a source cluster synchronizes data to a destination cluster is received, the data synchronization process traverses the to-be-synchronized data of the source cluster to obtain node data of a plurality of nodes in a tree structure corresponding to the to-be-synchronized data and a hierarchical relationship of the plurality of nodes, wherein a plurality of node data are respectively stored on the plurality of nodes; a first connection relationship between the data synchronization process and the destination cluster is established according to an Internet protocol address of the destination cluster; and the node data and the hierarchical relationship are sent to the destination cluster based on the first connection relationship, to instruct the destination cluster to create nodes according to the hierarchical relationship and store the node data into the nodes created by the destination cluster. The problems in the related art, such as complex operation and low efficiency, in data synchronization of a source cluster are solved. In the embodiment of the application, the data synchronization process obtains the node data of a plurality of nodes of a to-be-synchronized node and the hierarchical relationship of the plurality of nodes by traversal, and then the Internet protocol address of the destination cluster is input to the data synchronization process, so that the to-be-synchronized data can be synchronized to the destination cluster, which is very efficient.

[0034] In one example embodiment, the data synchronization process traverses the to-be-synchronized data of the source cluster to obtain node data of a plurality of nodes of the to-be-synchronized data and a hierarchical relationship of the plurality of nodes, including: determining, by the data synchronization process, whether an (i-1)th level node in a tree structure corresponding to the to-be-synchronized data exists, wherein i is a positive integer, 1≤i≤N, and N is a number of levels of the tree structure corresponding to the to-be-synchronized data; in the case that the (i-1)th level node exists, storing a node name of an (i+1)th level node of the (i-1)th level node into a to-be-recursed container, and determining node data and a hierarchical relationship of a 1st level node to the (i-1)th level node of the to-be-synchronized data.

[0035] Specifically, the data synchronization process traverses the tree structure of the source cluster, and determines whether each node in the traversal exists. In the case that each node exists, it is determined that the node is not a leaf node of the tree structure, i.e., the last node of the to-be-synchronized data has not been traversed, and a node name of a next level node of the (i-1)th level node is stored into the to-be-recursed container.

[0036] Optionally, the data synchronization process traverses the to-be-synchronized data of the source cluster to obtain node data of a plurality of nodes of the to-be-synchronized data and a hierarchical relationship of the plurality of nodes, including: the data synchronization process generally traverses the to-be-synchronized data of the source cluster; and the data synchronization process deeply traverses the to-be-synchronized data of the source cluster.

[0037] In an example embodiment, after determining, by the data synchronization process, whether the (i+1)th level node exists in the tree structure corresponding to the to-be-synchronized data, it is determined whether a node name exists in the to-be-recursed container in the case that the i th level node is traversed by the data synchronization process. The i th level node includes one or more i th level nodes. In the case that the node name does not exist in the to-be-recursed container, it is determined that the data synchronization process traverses from the 1st level node in the tree structure to the Nth level node in the tree structure. In the case that the node name exists in the to-be-recursed container, the data synchronization process accesses the (i+1)th level node based on the node name.

[0038] Optionally, in the case that the data synchronization process generally traverses the to-be-synchronized data of the source cluster, all nodes in the 1st level are traversed first, then all nodes in the 2nd level are traversed, and so on until all nodes in the Nth level are traversed.

[0039] In the embodiment of the application, in the case that each level of nodes is traversed, it is determined whether a node name exists in the to-be-recursed container. In the case that the node name does not exist in the to-be-recursed container, it is determined that the data synchronization process traverses from the 1st level node in the tree structure to the Nth level node in the tree structure, and then the traversal ends. In the case that the node name exists in the to-be-recursed container, the data synchronization process accesses the (i+1)th level node based on the node name, and continues to traverse the nodes according to the node name in the to-be-recursed container. Through the above embodiment, the hierarchical relationship of the nodes of the to-be-synchronized data and the node data contained in each node can be completely obtained.

[0040] In an example embodiment, after determining, by the data synchronization process, whether the (i+1)th level node exists in the tree structure corresponding to the to-be-synchronized data, a storage step is performed: in the case that the (i+1)th level node does not exist in the tree structure, the node data and the hierarchical relationship of the 1st level node to the i th level node of the to-be-synchronized data are stored in a to-be-created node container. The storage step is repeated until the node data and the hierarchical relationship of the 1st level node to the Nth level node are stored in the to-be-created node container.

[0041] For example, the Nth level node includes an N1th level node, an N2th level node, and an N3th level node. After the node data and the hierarchical relationship of the 1st level node to the N1th level node are stored in the to-be-created node container, the node data and the hierarchical relationship of the 1st level node to the N2th level node are also stored in the to-be-created node container, and so on until the node data and the hierarchical relationship of the 1st level node to the N3th level node are stored in the to-be-created node container, and the loop ends.

[0042] In one example embodiment, after storing the node data and hierarchical relationship of the first level node to the Nth level node in the to-be-created node container, the second connection relationship between the data synchronization process and the source cluster is disconnected, and the first connection relationship between the data synchronization process and the destination cluster is established according to the Internet protocol address of the destination cluster; the node data and hierarchical relationship of the first level node to the Nth level node in the to-be-created node container are sent to the destination cluster based on the first connection relationship.

[0043] That is, in the case where all nodes have been traversed to leaf nodes, the process is disconnected with the source cluster, and resources are released; then the process creates a first connection relationship according to the Internet protocol address of the destination cluster input by the user, and then sends the node data and hierarchical relationship of the first level node to the Nth level node in the to-be-created node container to the destination cluster based on the first connection relationship, and the destination cluster creates nodes according to the hierarchical relationship and stores the node data in the nodes created by the destination cluster, solving the problems in the related art that data synchronization of the source cluster is complex to operate and has low efficiency, etc. In the embodiment of the application, the data synchronization process obtains the node data of multiple nodes to be synchronized and the hierarchical relationship of the multiple nodes by traversing, and then inputs the Internet protocol address of the destination cluster into the data synchronization process, so that the to-be-synchronized data can be synchronized to the destination cluster, which is extremely efficient.

[0044] In one example embodiment, establishing the first connection relationship between the data synchronization process and the destination cluster according to the Internet protocol address of the destination cluster comprises: establishing multiple data synchronization threads in the data synchronization process according to the number of the destination clusters, wherein the number of the multiple data synchronization threads is the same as the number of the destination clusters; and establishing the first connection relationship between the multiple data synchronization threads and the multiple destination clusters according to the Internet protocol addresses of the multiple destination clusters.

[0045] It should be noted that the process creates the same number of threads as the number of Internet of Things addresses of the destination cluster input by the user to synchronize data, and the threads are executed in parallel, and the multiple threads are connected to the destination clusters, so that the destination clusters create nodes according to the hierarchical relationship, and after all threads are ended, the connection with the destination clusters is closed and resources are released, so that the synchronization of data is completed.

[0046] In an example embodiment, establishing the first connection relationship between the data synchronization process and the target cluster according to the Internet protocol address of the target cluster comprises: obtaining a key corresponding to the target cluster and verifying the key; in a case where a verification result satisfies a first preset condition, obtaining an Internet protocol address of the target cluster and a verification value of the target cluster; determining an interface corresponding to the target cluster according to the Internet protocol address and the verification value, and establishing the first connection relationship between the data synchronization process and the target cluster through the interface.

[0047] In the embodiment of the application, in order to enhance the security of information transmission, the data synchronization process needs to perform security verification on the target cluster before establishing the connection relationship with the target cluster. Specifically, a key corresponding to the target cluster is obtained and the key is verified. In a case where the verification is passed, an Internet protocol address of the target cluster and a verification value of the target cluster are obtained. An interface corresponding to the target cluster is determined according to the Internet protocol address and the verification value, and the first connection relationship between the data synchronization process and the target cluster is established through the interface. In a case where the verification is not passed, the connection relationship with the target cluster is refused to be established.

[0048] In order to better understand the process of the above data synchronization method, the implementation method flow of the above data synchronization is described below in combination with optional embodiments, but is not used to limit the technical scheme of the embodiments of the application.

[0049] In the embodiment, a data synchronization method is provided, Figure 3 is a schematic diagram of the data synchronization method according to the embodiment of the application, as Figure 3 shown, the specific steps are as follows:

[0050] Step S301: a connection relationship with a source cluster is established according to an Internet protocol address of the source cluster.

[0051] Step S302: to-be-synchronized data of the source cluster is obtained.

[0052] Step S303: node data corresponding to a current node is obtained by iteration.

[0053] Step S304: whether the current node has a next-level node is judged. In a case where the current node has the next-level node, step S305 is executed, otherwise, step S306 is executed.

[0054] Step S305: a node name of the next-level node is put into a node container to be recursively processed.

[0055] Step S306: node data and a hierarchical relationship of the current node are put into a node container to be created.

[0056] Step S307: determine whether all nodes of the level corresponding to the current node are traversed, if all nodes of the level corresponding to the current node are traversed, execute step S303, otherwise execute step S308;

[0057] Step S308: determine whether there is a node name in the container to be recursively traversed;

[0058] If there is, it means that there is data that has not been traversed to the root node, and the recursive traversal is continued, if there is no node name in the container, it means that all nodes have been traversed to the root node, then the process is closed, the connection with the source zk cluster is disconnected, and the resource is released.

[0059] Step S309: the process creates the same number of threads as the number of ip addresses of the destination cluster according to the purpose of synchronizing data, the threads are executed in parallel, and are connected to the destination cluster respectively;

[0060] Step S310: create nodes according to the hierarchical relationship;

[0061] Step S311: store the node data into the corresponding node;

[0062] Step S312: close the connection with the destination cluster, and release the resource.

[0063] According to the embodiment of the application, the user only needs to input the ip of the source zk cluster and the ip of the destination cluster into the program, without other cumbersome operations. Through the multi-thread mode, data synchronization can be performed on multiple clusters at the same time, and the efficiency is extremely high. Even during the use of the cluster, data synchronization operation can still be performed, without the need to restart the cluster, to realize hot synchronization, and without affecting the services relying on the cluster. After the scheme is implemented, the user only needs to maintain the input ip of the program during use.

[0064] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be realized by means of software and the necessary general hardware platform, of course, it can also be realized by hardware, but in many cases, the former is a better embodiment. Based on such understanding, the technical solutions of the application can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a plurality of instructions for making a terminal device (which can be a mobile phone, computer, server, or network device) execute the method of each embodiment of the application.

[0066] The traversal module 42 is configured to, in response to receiving an instruction indicating that the source cluster synchronizes data to the destination cluster, traverse, by a data synchronization process, to-be-synchronized data of the source cluster to obtain node data of a plurality of nodes in a tree structure corresponding to the to-be-synchronized data and a hierarchical relationship of the plurality of nodes, wherein the plurality of node data are respectively stored in the plurality of nodes.

[0068] The sending module 46 is configured to send the node data and the hierarchical relationship to the destination cluster based on the first connection relationship, to instruct the destination cluster to create nodes according to the hierarchical relationship and store the node data into the nodes created by the destination cluster.

[0069] With the above device, in response to receiving an instruction indicating that the source cluster synchronizes data to the destination cluster, a data synchronization process is used to traverse to-be-synchronized data of the source cluster to obtain node data of a plurality of nodes in a tree structure corresponding to the to-be-synchronized data and a hierarchical relationship of the plurality of nodes, wherein the plurality of node data are respectively stored in the plurality of nodes; a first connection relationship between the data synchronization process and the destination cluster is established according to an Internet Protocol address of the destination cluster; and the node data and the hierarchical relationship are sent to the destination cluster based on the first connection relationship, to instruct the destination cluster to create nodes according to the hierarchical relationship and store the node data into the nodes created by the destination cluster, thereby solving the problems in the prior art that data synchronization of a source cluster is complex and inefficient, and in the embodiment of the present application, the data synchronization process obtains node data of a plurality of nodes of to-be-synchronized nodes and a hierarchical relationship of the plurality of nodes by traversal, and then the Internet Protocol address of the destination cluster is input to the data synchronization process, so that the to-be-synchronized data can be synchronized to the destination cluster, which is highly efficient.

[0070] In one example embodiment, the traversal module 42 is configured to determine, by the data synchronization process, whether a next-level node exists for an i-level node in the tree structure corresponding to the to-be-synchronized data, wherein i is a positive integer, 1≤i≤N, and N is a number of levels of the tree structure corresponding to the to-be-synchronized data; in response to determining that the next-level node exists for the i-level node, store a node name of the next-level node of the i-level node into a to-be-recursed container, and determine node data and a hierarchical relationship of a first-level node to the i-level node of the to-be-synchronized data.

[0071] In an example embodiment, the traversal module 42 is configured to determine whether there is a node name in the to-be-recursed container in the case that the i-th level node is traversed through the data synchronization process, wherein the i-th level node comprises one or more i-th level nodes; in the case that there is no node name in the to-be-recursed container, it is determined that the data synchronization process traverses from the first level node in the tree structure to the N-th level node in the tree structure; in the case that there is a node name in the to-be-recursed container, the data synchronization process accesses the next level node of the i-th level node based on the node name.
