Utilizing Multi-Cluster Virtual Warehouse for Auto-Scaling

How can you ensure that the auto scaling in a multi-cluster virtual warehouse is both cost-effective and does not start clusters immediately?

What is the correct value for Scaling Policy to achieve this?

Answer:

The Scaling Policy should be configured to delay the start of new clusters and ensure cost-effectiveness.

When planning to utilize a multi-cluster virtual warehouse with auto-scaling capabilities, it is important to configure the Scaling Policy so that it both delays the start of new clusters and is cost-effective. The correct value for a Scaling Policy to achieve this would typically involve setting a delay for the auto-scaling to trigger, allowing the system to handle short-term fluctuations without immediately starting additional clusters. This can be accomplished by specifying a cooling period or specifying a threshold for CPU utilization that must be exceeded before new clusters are started.

The exact value or policy settings would depend on the specific virtual warehouse technology being used and the usage patterns of your users.
