Answer: Utilize cluster pools to reserve VMs ahead of time, reducing job startup time.
The correct answer is to use cluster pools to reduce the startup time of the jobs. Cluster pools allow you to reserve VMs in advance, so when a new job cluster is created, VMs are allocated from the pool. Note: While VMs are waiting to be used by the cluster, the only cost incurred is for Azure. Databricks runtime cost is billed only once a VM is allocated to a cluster.
