如何判断我的Firebase节点是否被使用？

Question

Firebase offers some overall Analytics in their App Dashboard, however, I need to know whether my stored data are ever used or they are just lying idly on a per node basis .

Why? It's simple: we are learning while developing, which makes the app a very fast evolving one. Not only the logic changes, but also the data stored need to be refactored from time to time. I would like to get rid of abandoned and forgotten data. Any ideas?

In best case, I would like to know this:

1. When was a node used last time? (was it used at all?)
2. How many times was it used in 1h/24h/1w/1M?
3. Differentiate between read/write operations

So apparently the Firebase itself doesn't provide any of this.

The only way I can think of right now is to create wrappers for firebase query and write functions and either do the statistics in a client app or create a devoted node for storing the statistical data.

In case of storing the data in firebase, the wrapper for writing functions ( set , update , push , remove , setWithPriority ) is relatively easy. The query functions ( on , once ) will have to write in a successCallback .
