At the moment we've connected our current BI tool (Looker Studio) to Snowflake, by subscribing to Central Connect. We started using iSAMS Central but the pre-built dashboards didn't suit our purposes, and didn't offer enough configurability.
I'd like to Connect snowflake into BigQuery, as this will allow us to query it with our non-ISAMS data seamlessly. I've been working with the team at iSAMS and feel we're quite close, though there seems to have been a winter hiatus in progress. When and if we get this running, I'll post an update here.
