Abstract: A data storage method and apparatus, and a data read method and apparatus in order to resolve a technical problem that a data storage process is relatively complex. The data storage method includes receiving to-be-written first data in a first format from an application layer, obtaining a first mapping relationship between data in the first format and data in a second format, where the second format is a KeyValue format, and the first mapping relationship is used to indicate a row attribute and a column attribute corresponding to each value obtained by converting the data in the first format, converting the format of the first data into the second format according to the first mapping relationship in order to obtain second data, and storing the second data.
