When dealing with a large complex query, what should a user do to improve performance?

Rewrite the query
Scale up the cluster
Scale out the cluster
All of the above

The correct answer is: Scale up the cluster

Improving performance for a large complex query can indeed involve various strategies. Scaling up the cluster, which means increasing the resources allocated to the existing virtual warehouse, allows for more powerful processing capabilities. This approach can be particularly effective when the existing resources are insufficient to handle the query workload efficiently, leading to faster query execution times. By enhancing the resources such as CPU and memory, scaling up directly addresses performance bottlenecks that arise from heavy computation needs, making it a suitable option in many scenarios. While rewriting the query may optimize it, and scaling out the cluster (adding more clusters of the same type) can also enhance performance under certain circumstances, scaling up offers a straightforward and immediate boost to processing power, especially for complex queries that may require intensive calculations or data retrieval.
