One of the highlights of the 1.3 release announcement is that “Livedata nog supports tunable queries”. I did some searching but didn’t find much … Anyone knows what this means?
After watching @zoltan’s talk from last night at #meteornight, I think it refers to the last three options for Collection#find, which are listed here: http://docs.meteor.com/#/full/find
Basically it lets you avoid using the oplog when you don’t want to.
