The report IUUC_ANALYZE_TABLE_COLUMNS can be used to evaluate the selectivity of certain key fields of a table which is needed if the logging table entries for this table should be processed by multiple jobs in parallel.
In this case, you need to define a certain primary key field of the table as the field that us used to delimit the range of records processed by each of the parallel-running jobs. The delimitation is done by means of certain values of the delimitation field.
