Abstract: A data system comprising a primary server and a secondary server, where the primary server obtains a first partition instruction and a second partition instruction, partition data in a first data table according to a first partition key to obtain a first partition table, and send the second partition instruction to the secondary server. The first partition instruction includes a first partition key, and the second partition instruction includes a second partition key, which is different from the first partition key. The second partition instruction is for triggering the secondary server to partition data in a second data table on the secondary server according to the second partition key to obtain a second partition table, which is the same as the first data table.
