SPLIT_NBR_OF_FILES <# of files>
When using the partitioning file rule:
<file_part_ind> = ( <int_unique_key> % <nbr_of_files> ) + 1
<nbr_of_files> is configured by the SPLIT_NBR_OF_FILES configuration entry.
Note: Partitioning is currently only supported with a custom build containing the partition rule. Please contact your nearest FairCom office for availability.
