Abstract: A data processing method and apparatus, a device, and a non-transitory computer-readable storage medium are provided. A target data table is obtained that includes at least two index keywords corresponding to a target object. Metadata information corresponding to the target data table is merged to obtain a metadata management table. Feature mapping is performed on data in the target data table according to the metadata management table in order to obtain data features corresponding to the at least two index keywords in the target data table and in order to generate data feature tables. The data feature tables are merged to obtain an index table. A metadata management table is constructed through the metadata information of the target data table. An index table corresponding to the target data table is generated according to the metadata management table to implement the inverted index of the data through the index table.
