How to stop Firebase Realtime Database Unity SDK listener load all child data at start of application

this will help I had a similar requirement in my project where I wanted to get only the latest chat messages to a user joining an already active chatroom. I used timestamps to build a robust solution for this.
Database design:
FirebaseDatabase.DefaultInstance.GetReference("Timestamp").RunTransaction(mutableData =>
    mutableData.Value = ServerValue.Timestamp;
    return TransactionResult.Success(mutableData);
.ContinueWith(task => 
    long currentTimestamp = (long)(task.Result.Value);
    //Use this timestamp in the next step
logR.OrderByChild("timestamp").StartAt(currentTimestamp).ChildAdded += HandleChildAdded;

Retrieve child data from firebase realtime database

Hope this helps I'm assuming that you also have a path for your user data, such as "/users/". The data for the user record would therefore be returned by looking at "users/LlMNVWXvzLhmP24AKVciM2PvPVy2", for example.
The point of indexing your records as you've done by indicating which users are associated with a customer is just to make it easier to fetch data later on, particularly as your database scales.
    "customer" : "1510925e-0541-474f-93c1-10890934fda9"
    "customer" : "634f6b10-1def-496d-af44-834ae3c69c27"
  ...for many, many records...

it fixes the issue In order to stop this from happening, you need to remove the listener accordingly to the life-cycle of your activity. So, please use the following line of code:

Does that help I can't really tell what exactly your condition is really trying to express, but if you want just a single value a single time from the database (without listening to its changes over time), you can simply use addListenerForSingleValueEvent() to get a single snapshot of a node in the database.
If you're waiting for a value to appear that wasn't previously there, and you want to stop listening at the time it appears, what you're doing is fine. But you might want to listen more closely to the child of interest instead of its parent.

How to listener on realtime firebase database for get data dynamically by backend laravel and websocket ,without use jav

I hope this helps you . While the Firebase Realtime Database uses web sockets to communicate between the server and its SDKs, this protocol is not documented. The closest you can get with a public API, is to implement Firebase's REST Streaming API.
But you'll have a much easier time if you stick to one of the supported server-side or client-side SDKs. For the server-side such SDKs currently exists for Java, Node.js, Python, and Go.
