Consumption given in the Firebase Database

I’m having a doubt that’s making me nervous, and I couldn’t find the answer.

On Android, when we’re making an app, usually there are several calls to collect "the same" data from Firebase. For example, open the customer tab: make the call to the customer listing. The user opens again Activity, there is new call to collect this data and display in a Recycler view (for example!).

With each call this spends more "download"? For example, if the user accesses this Activity several times, will each time he accesses it consume more download? Or he picks up some cache?

From my tests... I couldn’t reach a conclusion.

If you actually spend more "download", any suggestions on how to get around this issue?

If anyone can help me, I’d really appreciate it!

Note: When you go to the console firebase->database->uso has the term "Downloads", this is what I’m referring to.

  • Bandwidth has nothing to do with the amount of data traffic. You can fill a bucket (amount of data) with a dropper (low bandwidth) or with a truck kite (enough bandwidth). What changes is the time of the procedure.

  • Okay, I’ll correct the terminology.

    I could not understand well the question, but setting the persistence of firebase the last downloaded data is cached in the app, only downloading new data
