Hi , I want to ask several questions about metrics.
1. Without having experiment viewed table in database , I guess we can't create any metric right? I need to merge any table with user id in experiment viewed table? Can someone explain me how does the metric creation work? If this is the case then I need to also put experimentation key in where condition ?
2. How does event based actions work? Like if I want use metric such as total users who clicked a specific button , do I have to do it in database or I can utilize segment?
