The Data Vault creates temporary files to split the values of the original data files to match the value range of the repartitioned data files. The Data Vault copies data from the original data file to the temporary file that corresponds to the minimum and maximum value range of the repartitioned data file. The number of temporary files the Data Vault creates for each original data file is the same as the total number of repartitioned data files. For example, if the final number of repartitioned data files is two, then the Data Vault creates two temporary files for each original data file. You specify the location of the temporary file storage when you repartition the data.

After the Data Vault splits the values of each data file to the value range of the repartitioned data file, the Data Vault creates the repartitioned data files. To create the repartitioned data files, the Data Vault merges all of the temporary files of the same value range. The Data Vault stores the repartitioned data files in the data file directory configured in the ssa.ini file. Then, the Data Vault registers the repartitioned data files to the Data Vault repository.
