Whats the order of calculation of particular audiences? If audience depend on another audience then the order of batch recalculation is crucial

My case is as below:Session1User spents more than 10 secs on a specific site Session 2:We personalize for that user a banner How to use that attribute  "timeOnPage": 10,in Audiences?Custom?  

@brekrut do you know what is the difference between DDA and UPS  

I deleted such a dataset but the profiles from that datasets still persists in RT CDP. Would they be removed?

How would you do such a use-case that user spent more than 10 sec on some specific site?

I use basic query to find a profiles which belong to audience (80k users). Why nothing is returned?? No error SELECT *from profile_snapshot_export_745b62c8_332c_4a79_970e_03660f18b752WHERE segmentMembership.DDA['22eb5450-7b52-4d42-a9bc-e5dea5d34955'] IS NOT NULL why on our demo sandbox I need to use...

It is not explicitly said in the documentation.

Which one to use when I would like to send audiences to V8?What are the differences? Which one for streaming and which one for batch? 

Do you know if I can download the manifest file for data ingestion for Data Landing Zone source connector? In the UI there is a curlIf I follow the instructions then at the final request I got the file with data but not the manifest .... (its dummy data   

Resolution:If some field groups are not visible for the user then if these attributes are populated on the profile then that user would not see that attributes. Just tested
