To reduce traffic my app checks on startup if its data is up to date. Only if not it subscribes to collections. The problem is I don't know when ground:db did finish initialization of my local collections when i start the app (i.e. loading from localstore).

When I do the "is up to date" check in Meteor.onStartup sometimes the local collection is not fully loaded yet (e.g. only 3 of 5 docs are loaded).

Or is there already an event fired?
