We are syncing about 40 collections from Atlas, some of the rather large with about 100.000 documents. Depending on network latency and connection speed, initial sync is between 30 seconds to 10 minutes. The collections are using relationships extensively.
I’d like to change this to sync in background so the app can open without waiting for the full download. However, data seem to sync randomly leading to a bad user experience as linked objects may or may not be available.
I was hoping I could priority my collections in the sync configuration but no option like that exists. Similar to the timeout option but forcing some collections to be fully downloaded and others async in background. Or setting some limits per collection, like top N documents to start with, rest in background.
How should we approach this? Any design patterns to investigate?
The obvious solution is splitting to different Realms. However, the app developers are very happy with the relationships within a single Realm that then would be lost.
