Abstract
A method and device for storing data in a distributed database according to a row storage mode and a column storage mode, respectively, the method including: when a change is detected in the data in the row storage mode, obtaining the target row data that has changed based on a preset synchronization policy; determining the number of original data copies and the number of redundant data copies based on the attribute information and the number of failure-resistant nodes of the target row in which the target row data is located; coding the target row data in accordance with a predetermined corrective coding algorithm based on the number of original data copies and the number of redundant data copies, generating coded data; and distributing each copy of the coded data equally by column or group of columns to different nodes in the distributed database for storage.
