Abstract

The invention provides a data storage method and device, a storage medium and an electronic device. The method comprises the steps that under the condition that it is determined that a target storagenode is newly added in a database, modifying metadata information of a data table in the database to determine the data storage range of the storage node in the database, and the storage node comprises the target storage node and an original storage node; changing first sending information of a to-be-processed request sent to the database, the first sending information being used for sending the to-be-processed request to the original storage node, and the to-be-processed request being used for requesting to process data stored in the original storage node; and sending the determined target migration data to a target storage node to indicate the target storage node to store the target migration data, the target migration data being data outside the data storage range of the original storage node. Through the method and the device, the problem of node expansion in the database in related technologies is solved, and the effects of effectively expanding the database and operating the dataare achieved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a data storage method and device, a storage medium, and an electronic device. Background technique [0002] As the total amount of data production in all walks of life has grown more and more rapidly in recent years, it has become difficult for single-node databases to simultaneously satisfy massive data storage and fast response to high-concurrency data access. Distributed databases emerged as the times require. They split data and data tables through multiple nodes, effectively alleviating the problem of massive data storage, and achieving high availability and low-latency data access through load balancing, HA, etc. has become a key point in the big data industry mainstream choice. However, as the total amount of data storage continues to increase, distributed database clusters will inevitably need to add new nodes for expansion to meet the business needs of larger data volum...
