Hi, @Dominique DUCHEMIN
Thank you for posting in Microsoft Q&A forum.
The size of the package depends on your filter criteria, I think the size is normal if your ADR contains so many products.
We know the limit for software updates in the ADR is 1000 software updates, so an ADR package could even be larger than your package size 215 Gb.
And I suggest we can use Deployed as an update filter for your automatic deployment rules, the software update filter can help avoid redeploying older updates.
