Abstract: A data storage method and apparatus. The method includes: determining a same column attribute of at least two data objects that are to be stored in a KeyValue type distributed database; determining a format of a row identifier of each data object of the at least two data objects, where the row identifier format includes the same column attribute and a data object identifier; determining a row identifier value of each data record of each data object according to the determined row identifier format of each data object; and storing each data record and the row identifier value of each data record, where the row identifier value of each data record is used as a primary index. The data storage method and apparatus in embodiments of the present invention can improve data query efficiency.
