Databricks Data Engineer Associate Question 520
Select 3You are setting up a new Databricks workspace in a multi-region environment and need to ensure optimal performance for querying and managing metadata. Which of the following actions align with the best practice of colocating metastores with a workspace?
- A
Deploy the metastore in the same region as the Databricks workspace.
- B
Use a centralized, cross-region metastore for all Databricks workspaces to simplify management.
- C
Ensure the metastore and the workspace are in different regions to distribute the load.
- D
Configure the metastore to reside in the same cloud provider as the Databricks workspace.
- E
Leverage region-specific metastores for workspaces in different regions.
Show answer and explanation
Correct answers: A, D, E
Explanation
Colocating the metastore with the Databricks workspace in terms of both region and cloud provider is a recommended best practice to minimize latency and ensure optimal performance. Additionally, leveraging region-specific metastores for multi-region setups avoids cross-region latency issues and ensures efficient metadata operations.
- A. Correct.
Deploying the metastore in the same region as the Databricks workspace minimizes latency and ensures optimal performance, which is a best practice.
- B. Incorrect.
Using a centralized, cross-region metastore can lead to high latency and degraded performance, making it an unsuitable option for this scenario.
- C. Incorrect.
Placing the metastore in a different region than the workspace increases latency and is not recommended as a best practice.
- D. Correct.
Ensuring the metastore resides in the same cloud provider as the Databricks workspace helps maintain compatibility and reduces potential integration issues.
- E. Correct.
Using region-specific metastores for workspaces in different regions ensures that each workspace has low-latency access to metadata, which aligns with best practices.
