Do collecting [partition] only stats on a daily basis for all tables will cause extrapolation process to never work ?
we have an after data loadnig daily morning job which collects [partition] columns stats for all tables, and using this method row count from RAS of the partition Histogram taken daily morning will always be very simillar to the current RAS.
IF my understanding is correct, we will need to only collect partition column stats for tables do not have stats, but we need to keep the values of the partition column histograms InSync with other stats so optimizer adapt stats with growth if needed ??
