Hi, are you saying that you want to import metrics from Cube.js into the GrowthBook dashboard, instead of using GrowthBook to send experiment data into a datasource like GA4 or Clickhouse etc.?
We do offer the ability to connect a custom data source, but that requires writing some SQL so that GrowthBook can fetch your experiment data.
Most of our customers use our statistics engine to generate metrics within GrowthBook based on the experiment data. There isn't a way to import metrics, just experiment data via SQL queries to your data source.
