MongoDB Aggregation Pipeline
This presentation will demonstrate how you can use the aggregation pipeline with MongoDB similar to how you would use GROUP BY in SQL and the new stage operators coming 3.4. MongoDB’s Aggregation Framework has many operators that give you the ability to get more value out of your data, discover usage patterns within your data, or use the Aggregation Framework to power your application. Considerations regarding version, indexing, operators, and saving the output will be reviewed. Example use cases will be demonstrated along with comparisons to GROUP BY in MySQL and the new operators being introduced in MongoDB 3.4.
