Webinar: Joins and Other Aggregation Enhancements Coming in MongoDB 3.2
Applications get great efficiency from MongoDB by combining data that is accessed together into a single document. There are however situations where it is more efficient to have references between documents rather than embedding everything into a single document. This led to joins being our most requested feature. MongoDB 3.2 addresses this through the introduction of the
$lookup stage in the aggregation pipeline to implement left-outer joins.
This webinar looks at
$lookup as well as the other significant aggregation enhancements coming with MongoDB 3.2—why they're needed, what they deliver, and how to use them.
