Optional stopping value for the execute aggregate process statement. Use this value to give the ratio of the growth size you want to allow during the materialization of an aggregate storage database, versus the pre-aggregation size of the database (Before an aggregation is materialized, the database contains only level 0 input-level data.)
number (see MaxL Syntax Notes)
A stopping value of 1.5 means that during the materialization of the aggregation, the aggregate cells are allowed to occupy up to 50% of the disk space occupied by the level-0 data.
