<p>The invention relates to a method for sorting a data set comprising long data records, in particular data records of variable length up to 32k bytes. To allow to use common SORT methods, the steps of reading an input data set comprising long data records, splitting said long data records into data segments of equal length, assigning unique segment numbers to each of said data segments, sorting said data segments, assigning sorted segment numbers to each of said sorted data segments, sorting said data segments by segment number, replacing said long data records within said input data with said sorted segment numbers of the respective data segments, thus reducing the size of said data records, sorting said reduced data records by their sorted segment number, and restoring said long data records by replacing said sorted segments with the respective data segments are proposed.</p> |
