Description

Technical Field

[0001] The present application relates to the technical field of cloud computing, and in particular to a data synchronization method, device, storage medium and electronic device. Background Art

[0002] In the current multi-cluster and multi-computer room scenarios, load balancing in related technologies often requires service consumers to subscribe to multiple clusters at the same time, and implement park priority load through the park ID configured by the consumer. Taking the dubbo framework as an example, the dubbo consumer can subscribe to multiple registration centers at the same time, but needs to configure the park ID of each registration center at the same time. The consumer preferentially loads its request to the provider on the registration center in the same park as itself, but for a single consumer, its park ID is fixed, which means that only when the registration center of the current computer room is completely down and disconnected will it reload the traffic to the provider of other computer rooms. Therefore, most of the time, the provider data subscribed from other computer rooms is useless, but it occupies a large amount of memory of the consumer, and maintaining a large number of connections and heartbeats also requires a large amount of additional io overhead; and the consumer subscribes from another computer room registration center, and the registration center of another computer room must maintain an additional long connection with it, maintain heartbeats, and push provider data, which also adds additional system resource overhead to the registration center, further resulting in low data synchronization efficiency between different server clusters.

[0003] Currently, no effective solution has been proposed to address the problem of low data synchronization efficiency between different server clusters in related technologies. Summary of the invention

For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] The present invention will be described below in conjunction with preferred implementation steps. Figure 1 is a flowchart of a data synchronization method provided according to an embodiment of this application. As Figure 1 shown, the method includes the following steps:

[0028] Step S101, a data synchronization method, characterized in that it is applied to multiple server clusters for registration services. Among them, each server cluster at least includes: an election management node, at least one data node, and at least one connection proxy node. The method further includes: registering multiple services provided by a service provider through a connection proxy node, where the multiple services at least include: interface services.

[0029] For example, as Figure 2 shown, it includes two server clusters (which can also be a registration center cluster) for registration services, that is Figure 2 cluster 1 and cluster 2 in

[0030] After setting up multiple server clusters, it is necessary to register multiple clusters provided by the service provider in the server clusters. Optionally, in the data synchronization method provided in the embodiments of the present application, registering multiple services provided by the service provider through a connection proxy node includes: receiving a service registration request sent by the service provider, where the service registration request is a request for registering multiple services; and in response to the service registration request, registering multiple services provided by the service provider in the server cluster.

[0031] For example, as Figure 2 shown, when the service provider performs service registration in the server cluster, it randomly selects a connection proxy node to initiate a service registration request. The connection proxy node receives and responds to the service registration request, and registers multiple services provided by the service provider. Through flexible registration of multiple services provided by the service provider in the present application, the subsequent data synchronization efficiency between different server clusters is improved.

[0032] Step S102, store the service information corresponding to each service in a data node.

[0033] Specifically, perform a hash calculation on multiple services registered by the connection proxy node in each server cluster, and save the calculation result to the corresponding data node in the server cluster.

[0034] Optionally, in the data synchronization method provided in the embodiments of the present application, storing the service information corresponding to each service in a data node includes: calculating the service parameters of each service according to a hash algorithm to obtain the service information corresponding to each service; and storing each service information in a data node.

[0035] For example, as Figure 2 shown, the connection proxy node performs a (hash) calculation on the service parameters of multiple services for which registration is initiated to obtain the service information corresponding to each service, and stores it in a hashed manner on the corresponding data node in the same cluster. Among them, the service parameters can be service names, method names, list parameters, etc. By retrieving the service information in multiple data nodes of the server cluster in the present application, the service information corresponding to each service can be quickly found, further improving the data synchronization efficiency between different server clusters.

[0036] Step S103, in different server clusters, synchronize multiple service information in the data nodes through an elected management node, so that the service consumer can obtain the required target service information.

[0037] Specifically, as Figure 2As shown in the figure, the service consumer sends a subscription request for the target service to Cluster 1. If the service information corresponding to the target service does not exist in Cluster 1, the election management node is used to continue querying the service information corresponding to the target service in Cluster 2, so that the service consumer can obtain the required target service information.

[0038] To improve the data query efficiency between different clusters, optionally, in the data synchronization method provided in the embodiments of the present application, before synchronizing multiple service information in the data nodes by the election management node in different server clusters, the method further includes: receiving, in the current server cluster, a service subscription request sent by the service consumer for subscribing to a target service; in response to the service subscription request, matching the target service information corresponding to the target service with multiple service information in the data node to obtain a matching result.

[0039] For example, as Figure 2 shown in the figure, when the service consumer subscribes to a service, it randomly selects a connection proxy node in Cluster 1 to initiate a subscription service request for the target service. The connection proxy node receives and responds to the service subscription request. The connection proxy node calculates the hash of the service information that the service consumer needs to subscribe to and matches it with the corresponding data node in the cluster to obtain a matching result. By calculating the hash of the target service that the service consumer needs to subscribe to and matching the calculation result with the corresponding data node in the cluster, the retrieval efficiency of the target service information corresponding to the target service is improved, and the data synchronization efficiency is further improved.

[0040] Optionally, in the data synchronization method provided in the embodiments of the present application, synchronizing multiple service information in the data nodes by the election management node so that the service consumer can obtain the required target service information includes: if the matching result indicates that the service information in the current server cluster matches the target service information, using the service information in the current server cluster as the target service information required by the service consumer; if the matching result indicates that multiple service information in the current server cluster does not match the target service information, synchronizing the service subscription request to other server clusters except the current server cluster among multiple server clusters through the election management node, so that the service consumer can obtain the required target service information.

[0041] Specifically, as Figure 2 shown in the figure, if the matching result indicates that the target service required by the service consumer does not exist in the service information stored in the data node of the current server cluster, the service subscription request is synchronized and sensed to other clusters through the election management node of the current cluster, further improving the data synchronization efficiency between different server clusters.

[0042] Optionally, in the data synchronization method provided in the embodiments of the present application, the service subscription request is synchronized to other server clusters except the current server cluster among multiple server clusters through the election management node, so that the service consumer can obtain the required target service information, including: determining the corresponding target data node in other server clusters according to the service subscription request; matching the service information in the target data node with the target service information to obtain a target matching result; if the target matching result indicates that the service information in other server clusters matches the target service information, then using the service information in other server clusters as the target service information required by the service consumer.

[0043] Specifically, the connection proxy node is used to perform a hash calculation on the required service information again to find the corresponding target data node of the target service in other clusters (corresponding to the target data node in the present application). If the service information in the target data node matches the target service information corresponding to the service consumer, then the service information in the target data node is used as the target service information required by the service consumer, further improving the data synchronization efficiency between different server clusters.

[0044] In summary, the data synchronization method provided in the embodiments of the present application is applied to multiple server clusters for registering services. Each server cluster includes at least: an election management node, at least one data node, and at least one connection proxy node. The method further includes: registering multiple services provided by the service provider through the connection proxy node, where the multiple services at least include: interface services; storing the service information corresponding to each service in the data node; in different server clusters, synchronizing the multiple service information in the data node through the election management node so that the service consumer can obtain the required target service information, solving the problem of low data synchronization efficiency between different server clusters in the related art. By synchronizing the service information in different server clusters through the election management node, the effect of improving the data synchronization efficiency between different server clusters is achieved.
