Read-only & non-realtime mode activated to improve browser performance
Message pops up in my project and I'm unable to delete the nodes as well
Also I read this https://groups.google.com/forum/#!topic/firebase-talk/qLxZCI8i47s
Which states :
If you have a lot of nodes in your Firebase (say thousands), we need to create a new element for each node and modern browsers simply have limitations of how many DOM elements you can add to a page
It says:
To resolve this problem, don't load your Firebase Dashboard at the root of your Firebase, but instead load it lower down in the hierarchy
I do not get what it means
How do I get back to my Realtime Dashboard?
When it detects that it's downloading too many nodes from your database, the Firebase Console stops using real-time mode and switches to read-only mode. In this mode it requires less work from the browser, so it is more likely that the browser will stay performant.
To get back to realtime mode, you have to go to a location that has fewer nodes. So say that you start loading the database at the root, that means that "pseudo address bar" at the top of the data tree will say:
https://<your-project>.firebaseio.com/
And then will show the list of items. Now click on the URL in that pseudo address bar and change it to:
https://<your-project>.firebaseio.com/<one-of-your-keys>
And hit enter. The data tree will reload with just the node from one-of-your-keys and down and will likely switch to realtime mode again.
