Firebase download data again from serveur

问题

I'm on android and I have a problem with firebase.

I was just checking my bandwitch with the cmd windows and I found out that if I add a new data to firebase, insteads of uploading the local caches it downloads all the data.

I have the persistence enabled so it shouldn't be doing that.

I have this configuration :

So basically a key with article in it.

I am just going to add one from the browser and load it on my phone.

I run firebase database:profile on my cmd windows and load it on my phone

Insteads of downloading only the new article (about 150B), it downloaded all of them... (3.54 KB)

Is this a normal behaviour?

I have the persistence enabled (it works offline!)
