This looks great and should solve a number of issues with the current API. I have an app that basically tracks donations for different campaigns. Getting total donations per campaign isn't easy with the current API. There is nothing like a "select sum()" statement in Parse. Basically I currently have to run a cron job on my machine that will periodically download all donations by campaign and update the total donations field on the campaign (the regular user account doesn't have privileges to edit the campaign object). This seems like it will be a much cleaner, saner way to take care of this type of task.
