New MongoDB $lookup aggregation operator in 3.2

From’s blog

The core tool in MongoDB’s analytics story is aggregation – it lets your create a pipeline through which your selected documents can be passed which can then perform various operations to burn down to the information you are after. You could say aggregate your orders table, and in the pipeline, have an operator which matched only a particular classes of product ordered, then another operator that grouped the total sales of each product class. The pipeline has until now only worked with one collection’s documents… it’s into this pipeline that MongoDB 3.2 is adding a $lookup operator to bring in data from another collection.


Any issue using Meteor 1.2.1 with Mongodb 3.2? Interested in using $lookup (JOINS) and encryption

I think there’s a few issues that they are still trying to iron out with MongoDB 3.2 Mongo 3.2 Is Available

I was hoping to use $lookup with in an effort to fix an issue I had with publishWithRelations and others because aggregate sounds like a better way of doing the lookups I am doing. Alas out of luck with that one :frowning:
