Explanation:
Cluster pools in Databricks are used to ensure that a set of pre-warmed clusters is readily available to run workloads. This means that when a job is submitted, it can be executed more quickly because there is no need to wait for a cluster to spin up. Therefore, if a data team needs to refresh an automated report as quickly as possible, they will want to utilize cluster pools to ensure that the job can be executed as quickly as possible.
Key Points:
- Cluster pools maintain pre-warmed clusters that are ready to execute jobs immediately
- This eliminates the cluster startup time (which can take several minutes)
- For time-sensitive reports that need to be refreshed quickly, cluster pools provide the fastest execution
- Other options (B, C, D, E) describe scenarios that would benefit from different Databricks features:
- B: Reproducibility is achieved through notebooks, version control, and Delta Lake
- C: Testing is done through development workflows and validation frameworks
- D: Version control is handled through Git integration and Databricks Repos
- E: Accessibility for stakeholders is managed through permissions and sharing features
