Databricks Data Engineer Associate Question 518
Select 3A data engineering team is setting up a Databricks workspace and needs to configure the workspace's metastore for optimal performance and reliability. Which of the following practices should they follow when configuring the metastore?
- A
Co-locate the workspace and the metastore in the same cloud region.
- B
Use a single metastore for all workspaces across multiple regions to simplify management.
- C
Ensure the metastore is configured in the same region as the majority of the data sources.
- D
Always choose the default region for the metastore, regardless of workspace location.
- E
Configure separate metastores for different cloud providers if hosting workspaces across multiple clouds.
Show answer and explanation
Correct answers: A, C, E
Explanation
Colocating the metastore with the workspace in the same region ensures optimal performance by minimizing latency. Additionally, placing the metastore in the same region as the majority of data sources avoids unnecessary data transfer costs and delays. When working across multiple cloud providers, it is critical to configure separate metastores to ensure each workspace operates efficiently within its cloud environment.
- A. Correct.
Co-locating the workspace and the metastore in the same cloud region minimizes latency and improves performance. This is a best practice.
- B. Incorrect.
Using a single metastore for all workspaces across multiple regions may simplify management but can introduce latency and performance issues due to cross-region communication.
- C. Correct.
Ensuring the metastore is in the same region as the majority of the data sources reduces data transfer latency and costs, aligning with best practices.
- D. Incorrect.
Choosing the default region for the metastore without considering the workspace and data location can lead to suboptimal performance and higher latency.
- E. Correct.
Configuring separate metastores for different cloud providers ensures that each workspace is optimized for its respective cloud environment, which is a best practice when working across multiple clouds.
