Abstract
A computer-implemented method for partition table data writing includes obtaining a first data row to be written into a first partition table and a current partitioning rule indicating at least that the first partition table includes a partitioning key that is a basis for dividing data rows to be written into logical partitions and a first quantity of partitions. A target logical partition corresponding to the first data row is determined. A target physical partition is determined, where the target physical partition has a globally unique partition identifier. The globally unique partition identifier of the target physical partition and an auto-increment identifier of the first data row to the first data row are added as a composite primary key value. The first data row with the composite primary key value is stored to the first partition table.
