I am using Realm and building a Swift mobile app. I am really struggling to understand why and when Partial realms are created.
Here is my scenario:
a user logs in to the app and is brought to the first view controller.
In the first view controller in view did load, I am executing a query to get the current user, subscribing to the query and adding an observer to let me know when the data is synced:
let currentUserArr = realm.objects(DBUser.self).filter("id == %@", userId)
self.subscription = currentUserArr.subscribe(named: "current user")
self.subscriptionToken = self.subscription.observe(\.state, options: .initial) { state in
switch state {
case .creating:
print("creating")
case .pending:
print("pending")
case .complete:
print("complete")
self.artist = currentUserArr[0]
case .invalidated:
print("invalidated")
case .error(let err):
//seal.reject(err)
print(err)
}
}
This makes sense that if I check Realm Cloud, I have a new partial realm created with path as:
/db/__partial/DyeOy3OR4sNsqMi2OmDQQEzUa8F3/~7f11cf52
However, here is where my confusion starts. I log the user out. I log back in and again the code above executes. My thought would be that Realm would just reuse the partial already created, but instead it creates an entirely new partial.
/db/__partial/DyeOy3OR4sNsqMi2OmDQQEzUa8F3/~8bc7bc49
Is this by design or should I somehow be reusing partials rather than having a new one created every time a query is executed (even if it is executed by the same user)?
I have posted on Realm Forums as well:
