Description

Data synchronization method, device, system, equipment and storage medium
Technical Field
The embodiments of the present invention relate to the field of data transmission technologies, and in particular, to a data synchronization method, a data synchronization apparatus, a data synchronization system, a data synchronization device, and a storage medium.
Background
A single-page Web application (SPA) limits all Web activities to one Web page, and once the Web page is loaded, the SPA does not reload or jump the page due to the operation of the user, but dynamically transforms HTML content by using JavaScript, thereby providing smooth user experience.
In the distributed cluster, users access the corresponding partition cluster according to the user partitions, and when a user of a certain user partition modifies the general data in the front-end SPA used by the user, the modified data needs to be synchronized into the front-end SPAs used by users of other user partitions, namely, the data needs to be synchronized across the partition clusters.
The communication of Web application is based on HTTP protocol, a request is initiated by a browser, a server cannot actively push, and data is synchronized in the Web application in the prior art in a short round robin mode and a long round robin mode, wherein short polling refers to that the browser sends HTTP requests to the server at preset time intervals to obtain the latest data, and after the server receives the request initiated by the browser, the server does not directly respond, but firstly hangs the request, then judges whether the data of the server is updated or not, responds if the data of the server is updated, and returns the response after a certain time if the data of the server is not updated.
In summary, synchronizing data in a short round robin manner easily causes a large number of clients to continuously send HTTP requests to a server, which undoubtedly increases the server pressure and reduces the speed of processing requests by the server, and meanwhile, due to the interval time between request sending, the real-time performance of data synchronization is poor, and different partition servers cannot know that data synchronization is needed; and suspending requests by synchronizing data in a long round-robin manner leads to resource waste, each request follows an HTTP protocol, and an HTTP header is brought each time, which causes waste in transmission, and different partition servers also cannot know that data synchronization is required.

As shown in fig. 7, in this example, a client in the first partition modifies common data and needs to synchronize the common data to a client in the second partition and other clients in the first partition, when the client in the first partition requests for synchronizing data, the WebSocket server in the first partition stores the synchronizing data in the database and pushes the synchronizing data to other clients in the first partition, so that the other clients in the first partition synchronize local data according to the synchronizing data, and meanwhile, the WebSocket server in the first partition updates data configuration on the etcd and generates a synchronization message on the etcd, and the etcd notifies all second partition socket servers subscribed to data synchronization service of the synchronization message, and all second partition WebSocket servers acquire the synchronizing data stored in the database and push the synchronizing data to the clients in the second partition, and the clients in the second partition synchronize local data according to the synchronization data. In fig. 6 and fig. 7, the first partition and the second partition are taken as examples to illustrate the data synchronization method according to the embodiment of the present invention, and in practical applications, the data synchronization method may further include multiple partitions, and the embodiment of the present invention does not limit the number of the partitions.
In the above example, because the WebSocket server of the first partition receives the data synchronization request sent by the client of the first partition, and stores the synchronization data carried in the data synchronization request in the database, updates the data configuration on the etcd distributed storage cluster to generate the synchronization message, and sends the synchronization message to the WebSocket server of the second partition, the WebSocket server of the second partition acquires the synchronization data from the database according to the synchronization message, so as to push the synchronization data to the client located in the second partition, thereby implementing data synchronization of each partition in the distributed cluster, and because the partition server is the WebSocket server, the WebSocket server acquires the synchronization data from the database and actively pushes the synchronization data to the client of each partition needing synchronization when the etcd distributed storage cluster subscribes to the synchronization message, the real-time performance of data synchronization is high, and the client does not need to send a request, and does not need to hang up a request, thereby reducing the processing pressure of the server, and saving transmission resources.
