I have a dashboard with 4 questions/cards that use the same view. How many queries does metabase send down to Postgres when it first renders the dashboard? The first time rendering the dashboard takes significant time to render but after the first time each refresh of the browser is very fast. I understand that there is caching happening, but I would like to understand how Metabase sends the queries to the database on the initial rendering of a dashboard. If I have 4 questions that are querying the same view, is it sending 4 separate queries to the database or just one since they are all going against the same view?
