But it not there a data retention policy? Can we see all the data for a profile or last 7 days or 30 days or all the data. Thanks in advanced 

When Event data ingested into profile and then if I view in UI - Profile-browse should I see only last 7 days data for profile? All data for the profile including failed rows?
