Managing Online Presence in Cloud Firestore

Question

In Firebase Realtime Database, we can easily manage User presence by keeping a reference to a node and updating it as shown below:

DatabaseRef presenceRef = FirebaseDatabase.getInstance().getReference("disconnectmessage");

presenceRef.onDisconnect().setValue("I disconnected!");

If I want to do the same in Cloud Firestore, is there any way to achieve it?

You can easily use both Cloud Firestore and Realtime Database in the same project. For presence, we recommend you still use the Realtime Database to handle it.

There is a section in the documentation on how to use the Realtime Database to store user presence in Firestore.
