Having trouble understanding a something on experimentation and integration with Segment. 1. On the reporting side, how can I know a purchase was made via an experiment? It’s clear that we would have a table in Snowflake with the Experiment Viewed events from Segment, but it’s not clear how we would join that with save a bookings/revenue table. https://docs.growthbook.io/event-trackers/segment. I do see the experiment assignments queries in my data sources, I am wondering how that gets joined with the metrics query for an experiment
we join based on the randomization unit you've assigned in the experiment report - so we pull a list of users (typically users, but could be anything) and then join by that id to other metrics like bookings or revenue. As long as those metrics can return a user id that can be joined back to the assignment id
