I'm hoping to share a looker studio dashboard with a customer via a public URL. The dash is filtered via a parameter in the URL.
I'm concerned that if somehow this link was to be shared publicly, we might rack up a large a BQ bill for querying the data. We've taken measures to avoid this and can revoke links very quickly.
I've set the data freshness to 12 hours and I understand that looker caches data but does anyone know whether heavy usage would generate costs beyond the data pull every 12 hours?
For example, if a user views the dash 1000 times, will we be billed for 1000 queries? Similarly, if 100 users viewed the dash, do we get billed for each new session/user?
