Which query will identify the specific days and virtual warehouses that would benefit from a multi-cluster warehouse to improve the performance of a particular workload?
Which query will identify the specific days and virtual warehouses that would benefit from a multi-cluster warehouse to improve the performance of a particular workload?
To determine which days and virtual warehouses would benefit from a multi-cluster warehouse setup, we need to assess the load on the warehouses. Option B effectively does this by summing the average running and queued load for each warehouse per day. The HAVING clause is correctly used to filter records where the sum of the average queued load is greater than zero, indicating periods of time when additional resources or clusters would have been beneficial to handle the load.
I think B, because is the only one that uses the HAVING clause correctly (with an aggregate). The rest ones would use WHERE instead of HAVING
Should D.
