As a matter of fact, we took the extreme approach of not allowing customers (or ourselves) to set any of the known knobs. We want to force ourselves to build the best the system to run well out of the box and yet still beats data warehouses in price perf. The official result involved no tuning. It was partitioned by date, loaded data in, provisioned a Databricks SQL endpoint and that’s it. No additional knobs or settings. (As a matter of fact, Snowflakes own sample TPC-DS dataset has more tuning than the ones we did. They clustered by multiple columns specifically to optimize for the exact set of queries.)
