When you add .fromLocalDatastore to a PFQuery, does it query exclusively the local datastore, or does it query the cloud as well?
From Parse:
Often, you'll want to find a whole list of objects that match certain criteria, instead of getting a single object by id. To do that, you can use a PFQuery. Any PFQuery can be used with the local datastore just as with the network. The results will include any object you have pinned that matches the query.
A PFQuery query using .fromLocalDatastore() does not hit the cloud.
The reason is that is its behavior by definition but I also verified this to be true through network monitoring of a query both with and without the use of .fromLocalDatastore().
