MongoDB Aggregations for Product Analytics When SQL Would Hurt

Sometimes the document model matches how you ingest events—but you still need readable aggregates.

I share aggregation pipeline patterns we use for funnels and rough cohort views, and when we push data to a warehouse instead.

What you'll learn

• Practical $match / $group building blocks
• Index hints that keep pipelines fast enough
• When Mongo is the wrong place for BI

Next steps

If the pipeline is 200 stages, question the schema before you optimize.
