问题
Looking at Realtime API quickstart example, a shortcut file is used to store realtime document model. I'm assuming that this is a file that holds realtime document model state.
Question: do I need to create and clean up this shortcut file for each collaboration session?
Note: Eventually I want to persist data to my database, not Google Drive.
回答1:
From an API perspective, the realtime documents are designed to be persistent storage. The files are long lived, and there is there is no need to ever recreate them or store data elsewhere.
If you want to copy data elsewhere, how and when to do that sounds like a design decision you need to make given whatever makes sense for your app.
