As a product manager I want telemetry in the agg pipeline builder so I can see how our customers use the interface. Interesting questions to ask:
- How long was spent building the pipeline?
- How many stages was the pipeline?
- What are the most frequently used stages?
- What are some common mistakes made?
- What is the size of the sample set by users?
- How often does someone get stuck writing a pipeline / fail to create a valid pipeline?
