Big query does not show schema

The schema is not visible (toggled it on in the data connector). I guess because ‘bigquery-pubic’ is connected and there are many tables there. Any way to tell the connector to connect to a specific DB or table?

The BigQuery query_runner doesn’t have this feature (we’d happily merge an improvement to support it).

But you can probably achieve the same thing with permissions controls in the BigQuery cloud console. Just grant to the service account Redash uses SELECT permission only on the DB or table(s) you want to examine with Redash.
