Webinar: What's New in Aggregation

In this webinar, we will introduce MongoDB’s new aggregation system that simplifies tasks like counting, averaging, and finding minima or maxima while grouping by keys in a collection. The new aggregation features are not a replacement for MapReduce but will make it possible to do a number of things much more easily without having to resort to the big hammer that is MapReduce. After introducing the syntax and usage patterns, we will give some demonstrations of aggregation using the new system.
