Realtime Database
The Realtime Database functionality includes dynamic updates via the server-sent events protocol as implemented by Firebase. As such, database updates can happen and everyone connected to any path that's updated will be updated directly without the need to do a get at that path. This will store the data automatically for you as well and send a signal with the latest info.
