I am trying to do some benchmarking for some query patterns. Multiple runs aren't very useful as snowflake returns the result immediately using QUERY RESULT REUSE node. Is there a way to force snowflake to re-compute the query?

Suspending and restarting a warehouse or using a new warehouse doesn't help with this.

  • I still want the cache effects to exist while benchmarking because that's closer to what the real case looks like

I solved this by adding CURRENT_TIMESTAMP() as one of the projected columns. This forces the query optimizer to recompute results as the function isn't deterministic.
