Abstract
A method for updating a data table in a KeyValue database is provided. Raw data is received and formatted into a data updating file. An update timestamp is set for each column qualifier in each row of the data updating file. A data deleting file is generated. A delete timestamp is set for each row of the data deleting file. Each row of the data deleting file corresponds to one row of old data in the data table. Each row of the data deleting file includes a row key that is the same as the row key of the corresponding row of old data in the data table. The data updating file and the data deleting file are both imported into the data table. Consequently, timestamp is used to indicate the valid data in the data table. An apparatus configured to perform the method is also provided.
