Can real-time apply in SRLs replace archived logs from primary database?

in High Availability Data Guard, Sharding and Global Data Services (MOSC) 3 commentsAnswered ✓

I am running Oracle 19c dataguard (asynchronous, maximum performance on local hardware) and have a question regarding the need for the primary database to send archive logs to the standby site if real-time apply is running. If real-time apply is configured and SRLs are being updated in real-time, is it necessary to send the entire archivelog file to the standby site? Isn't this a duplication of data in transit? Couldn't the standby site ARC process create archived logs using the SRLs after a log switch?

The reason I ask is that it appears network glitches are occasionally blocking archived redo logs from shipping - but if the real-time apply catches the redo as it happens - instead of trying to fetch the archived log from the primary, how about just use the SRL to create the archived log?
