Realm not opening when offline #7883
Description
How frequently does the bug occur?
Always
Description
Expectation :
Realm.getInstance() to load faster whether online/offline like any other offline library and continue read/write ops. And Realm check network connection, sync in background.
What actually happened :
Realm not behaving like offline-first. Works like online-only. Realm is not opening in Offline mode and taking very long in online.
When online, Realm.getInstanceAsync takes long time to load, based on network speed. On fast network it takes ~1000ms and on slow network it takes almost 10-20 seconds.
This freeze the UI and makes it unsable.

Reproduction Steps
Here is my code:
long startTime = System.currentTimeMillis();
app = new App(new AppConfiguration.Builder("app-id").build());
if (app.currentUser() != null) {
Log.e(TAG, "onCreate: Realm user already logged in uid -> " + app.currentUser().getIdentities());
SyncConfiguration config = new SyncConfiguration.Builder(app.currentUser())
.initialSubscriptions(new SyncConfiguration.InitialFlexibleSyncSubscriptions() {
@Override
public void configure(Realm realm, MutableSubscriptionSet subscriptions) {
subscriptions.addOrUpdate(Subscription.create(
realm.where(RealmCustomerModel.class).equalTo("uid", app.currentUser().getId()))
);
subscriptions.addOrUpdate(Subscription.create(
realm.where(RealmTxnModel.class).equalTo("uid", app.currentUser().getId()))
);
}
}).build();
Log.e(TAG, "Realm getInstance/Async started");
Realm.getInstanceAsync(config, new Realm.Callback() {
@Override
public void onSuccess(Realm realm) {
uiThreadRealm = realm;
Log.e(TAG, "onSuccess: Realm getInstanceAsync success in " + (System.currentTimeMillis() - startTime) + "ms");
populateUi();
Realm.setDefaultConfiguration(config);
}
});
}Is the configuration correct or am I doing something wrong?
