A large table with 200 columns contains two years of historical dat

a. When queried. the table is filtered on a single day Below is the Query Profile:

Using a size 2XL virtual warehouse, this query look over an hour to complete

What will improve the query performance the MOST?

Show Suggested Answer Hide Answer
Suggested Answer: B

This option is the best way to configure the compute resources to support this dashboard. By assigning all queries to a multi-cluster virtual warehouse set to maximized mode, the Data Engineer can ensure that there is enough compute capacity to handle thousands of concurrent queries from different analysts. A multi-cluster virtual warehouse can scale up or down by adding or removing clusters based on the load. A maximized scaling policy ensures that there is always at least one cluster running and that new clusters are added as soon as possible when needed. By monitoring the utilization and performance of the virtual warehouse, the Data Engineer can determine the smallest suitable number of clusters that can meet the responsiveness requirement and minimize costs.

I bet the query would run even faster if they had a virtual warehouse the size of a small country. Someone call the infrastructure team!

Increasing the number of clusters? That's like trying to fit more socks in a drawer - it might work, but it's not addressing the root problem.

Implementing the search optimization service? Isn't that kind of like putting a Band-Aid on a broken leg?

Adding a date column as a cluster key sounds like the most logical solution. That way, the query can leverage the table's organization for faster results.

Increasing the virtual warehouse size seems like a brute-force approach. I'd rather optimize the table structure first.

Maybe increasing the size of the virtual warehouse is necessary for handling large amounts of data.

I'm not sure. Maybe implementing the search optimization service on the table could also help improve performance.

I agree with Kris. A larger virtual warehouse can handle more data and process queries faster.
