title: Trouble Exporting JSON in Firebase Read-only & Non-realtime Mode
body: <p>It seems like when the amount of data gets too large, Firebase goes into a "Read-only &amp; Non-realtime Mode" which they didn't warn about. In this mode, the Export JSON does not work. I can go into each and every node to extract the JSON, but that will mean that I have to do for tens of nodes. How do I get the node (that is currently too large) to become real time again, or how do I export the JSON when it is non-realtime? Also, is Firebase still writable when it is in non-realtime?</p>
