I have consulted this documentation and this documentation and this Trailhead material, but I can't find a concrete answer on this. If I use Data Retention, can I configure it so that it only deletes specific records older than X days within a Data Extension?
For instance, say I have a Data Extension named myDE, and it contains some records that are 8 days old, and other records that are 2 days old. Say I specify Retention settings on this DE of "Individual Records" and "After 7 Days". When the nightly deletion process runs, will it ONLY delete the 8-day-old rows, and leave my 2-day-old rows intact within the DE?
