Sort Details

In order to perform the data load FastStats has to join the tables, this can be done either by using indexes or by sorting the input files into the correct order for the join. Alternatively if the files are already supplied in the correct sort order then FastStats Designer can skip the sorting process entirely and build directly from the pre-sorted input files. Pre-sorting the input files can dramatically improve the data load speed but the sort order can be complex. Please see the page Improving Load Performance for details on how to pre-sort the input files.

Auto-sort all input files

If the input files have been pre-sorted into the correct order for the data load then unchecking this box will prevent FastStats from sorting the input files. Please see the page Improving Load Performance for details on how to pre-sort the input files.
