Hi, I'm using the GrowthBook Ruby SDK and have set up BigQuery as my data source. I'm currently sending experiment exposure events to BigQuery from my backend. Do I also need to manually send goal/conversion events (such as bookings or clicks) to BigQuery for GrowthBook to analyze experiment results? Or is there a built-in mechanism in the Ruby SDK or GrowthBook platform that can automatically track and store these goal events in BigQuery?

There's nothing built in for that. Generally, there's an event tracker (Segment/GA4) that sends that data, which you use to define metrics in GrowthBook. So, you could reach for an event tracker or you would also need to send that data to BQ yourself.
