Abstract
A data partitioning method and apparatus. The method includes: determining tuple relationship information according to received mixed loads and structure information of a database; determining tuple split cost information according to the tuple relationship information and a feature about whether the mixed loads are executable in parallel; obtaining multiple partitioning schemes according to the tuple split cost information, and determining, from the partitioning schemes, a partitioning scheme with a minimum total cost value as an optimum partitioning scheme to perform partitioning processing on data stored in the database. In the data partitioning method and apparatus, optimum partitioning is performed on data associated with the mixed loads in a database, after partitioning, data has features of a transaction load and an analytical load in the mixed loads, thereby improving working performance of the database system oriented to the mixed loads.
