Further, when the data node 3306 is also changed, neither the database cluster nor the client node for data update can be used, and the client cannot obtain the data used to continue running, resulting in the client being unable to continue running
[0004] To sum up, in the existing technology, when the data node used for data update between the database cluster and the client is changed, the client side fails to synchronize the changed data node information in time, which may easily affect the operation of the client

The invention provides a link configuration adjusting method and device. The method includes the steps that first data node information of a database cluster is obtained every preset time; the first data node information is compared with second data node information, locally stored by a client side, of the database cluster so that a comparison result can be obtained; according to the comparison result, link configuration is adjusted. According to the link configuration adjusting method, the data node information of one side of the client side can be adjusted in time, it is guaranteed that the client side can use newest data node information for obtaining data needed for operation from the database cluster, and the operation efficiency of the client side is improved.
Description
technical field [0001] The invention relates to the field of data storage, in particular to a link configuration adjustment method and device. Background technique [0002] In the prior art, when using the database cluster to update the data of the client, if the data node used for the data update is changed (for example, deleted or replaced), the information of the data node before the change is still saved in the client, especially the database When all the data nodes available to the client in the cluster are changed, the client of the client cannot link to the required database according to the locally stored data node information, which may affect the normal operation of the client. [0003] For example, data update is performed between the database cluster and the client through the data node 3306 and the data node 3307. Among them, 3306 and 3307 are identification numbers of each node. After the data node 3307 is replaced, if the client is not notified in time that ...
